I'm looking for a good wysiwyg editor with image upload functionality (i.e. a user can add as many pictures as he likes, form URL's or disk, and they'll be uploaded).
I already tried TinyMCE, but it was really heavy and took a very long time to load (I'm using JEditable to only make the editor appear when the user clicks on it).
I've used the components from dhtmlx.com and had pretty good success with them. You can buy the libraries or use the open source version of them if your project qualifies.
You can find the editor library here: http://dhtmlx.com/docs/products/dhtmlxEditor/index.shtml

I'm trying to figure out how to upload images with CK Editor 5. Now I've seen a whole size of different plugins, but I would like to learn how this works for myself. What I have noticed is that if I click the image button, I get a dialog to upload the image and then I select an image and nothing happens.
Based on the guides and articles I have been reading, my assumption is that I have to save the image to the server and then give the url back to the ckeditor so that it may use it to display the image.
What I can't seem to figure out is how to do that. Where in the ckeditor js code would I add my own logic so that it may pick up the uploaded image, send it to the server and then give a url back to ck editor?
I've been through a lot of documentation such as this, but I can't seem to find anything.

Did you check the console? On the console, if you don't have the editor properly configured, you'd have something like this:
filerepository-no-upload-adapter: Upload adapter is not defined. Read more: https://docs.ckeditor.com/ckeditor5/latest/framework/guides/support/error-codes.html#error-filerepository-no-upload-adapter
Now, there are two built-in upload adapters – for CKFinder's server connector and for the Easy Image service provided by CKEditor Cloud Services. Both need to be configured to work:
CKFinder adapter: https://docs.ckeditor.com/ckeditor5/latest/api/module_adapter-ckfinder_uploadadapter-CKFinderAdapterConfig.html
Easy Image: https://docs.ckeditor.com/ckeditor5/latest/features/image-upload.html#easy-image
The role of an upload adapter is to expose a function which will send a file to the server (in whatever way it wants) and notify the editor once the upload is done (by returning a URL to this file). The editor takes care of the rest – inserting the image into the content, displaying a progress bar, etc.
Besides using the built-in adapters, you can write your own one. See:
https://docs.ckeditor.com/ckeditor5/latest/api/module_upload_filerepository-Adapter.html
https://github.com/ckeditor/ckeditor5-adapter-ckfinder/tree/master/src as an example of a simple upload adapter
I have a blog website that loads the images slowly i want to know how to make them load faster and:
I am using same image for thumbnail and story. thumbnail is small,does it still load full image?if so how to use thumbnail of an image?
Where should i store the images? what is the best location to store images for your websites and blogs? can save them in one drive and use the source?
how to optimise images?what is a placeholder?i have seen many websites such as facebook use a kind of place holder which displays before image and content?how to do so?
-how to i preload images ? or is there any better way ?
Here are some pointers.
Thumbnail images have to be separate from original (large) images. When the user uploads the images, you have to use some script to resize the images. If you are using a standard CMS like Drupal or Wordpress, there should be an option somewhere to do the resizing (without you having to write code).
Assuming your blog is public, the images as well should be public (usually). You can create a directory named files and you can store the images inside that directory. If you are using a standard CMS, these options should be there in some form.
To avoid having all files in one directory in the long run, use folder naming schemes like files/[YEAR]/[MONTH] or anything else you think would serve your purpose.
Make sure the uploads directory and your upload mechanism is well-protected using and .htaccess (or equivalent). Otherwise, someone might upload malicious scripts and execute them on your server.
A placeholder is anything which holds the place of something while the original thing is absent (or being loaded). So, a placeholder image will be a standard image with a general design - it's as good as saying loading. You can use JavaScript or CSS (background-image) to achieve such a placeholder.
Preloading should not be necessary as far as I see from your question. A better opinion / answer could be given if you share the link to your site.
Next time, please try to make detailed questions - one question per problem, if possible. Also, do not fear to Google for a solution. I learnt programming (PHP, JS, Drupal, CodeIgniter and more) just by Googling! Hope this helps!
Jigar has done a fairly good job of answering the question though I thought I'd add if you want to optimise images there are plenty of websites that do it for you for free.
My favourite is https://tinyjpg.com/ however there are plenty of others. A quick Google search will get you plenty of different sites all doing basically the same thing.

I was looking at this question Download image with JavaScript which shows how to download an image.
I want to be able to do something similar but more automated. I would like to navigate to an imgur page, enter some search parameters then use jQuery to download any .jpeg or .png
I have the basic layout
navigate to imgur and search
find all .jpeg and .png in page
run code similar to other question to download
What I want to know, is can I specify a specific folder to save the images to?
Can I automate the click of the Save button?
If this is not possible in pure jQuery/javascript my other choice is to default to using iMacros with some javascript mixed in, I would however like to avoid this.
This is not possible using only JavaScript.
A user's interaction will always be required in order to save a file. Imagine the mess we'd be in if that weren't the case... Viruses everywhere!
Is there a way to implement functionality so that a user can Right click a subsection of an Html page (say a DIV or other container element) so that that part can be saved as an image/pdf (using javascript)?
Alternatively (ideally) can this be done on the server side in ASP.NET?
The use case for this is the following:
I have some complex web pages generated in asp.NET and using the javscript Flot library for the graphs. I would like to reuse part of the html page to generate PDF reports or at least image snapshots which can easily be inserted into reports. I have looked around and it seems there is a tool wkhmltopdf which converts the entire page to PDF, however there are 2 issues:
This tool needs to be run separately, which is not friendly for end users
The tool extracts everything on the page, e.g. menus headers , footers etc.
For the second problem I could generate web pages without the headers/footers and menus, and then use the tool, but this does not solve problem 1. Ideally I would like to generate the report weekly and automatically so the user only needs to download it.
For this purpose what is really needed is some way to store as pdf or image a DIV (or other element) referenced by id. This way I would not need to write separate code to generate the reports. I realize there will be a loss of quality converting html to PDF, but for our purposes, this is not that important.
IECapt# is a new and experimental version of IECapt written in C# to render a web page into a BMP, JPEG or PNG image file.
see http://iecapt.sourceforge.net/
You will have to make some calculations, if you want to crop the captured image to your requirements, or give the tool the html u actually want as an image,instead of the whole page.
Hope this helps.
In case this can help others, I finally settled for the iTextSharp library which is very powerful and also handles svg. It does not do the general html5 to pdf dump but with a bit of code I can do most of what I need.

Has anyone ever found any lightbox type javascript / css code that can display PDFs? I have tried many libraries and none have worked for me. The environment needs to be IE6/IE7 compatible.
I am looking for something similar to this:
Lightbox 2
http://stickmanlabs.com/lightwindow/
Specifically, check out the demo "Flash Paper" for embedding PDFs
Good luck finding anything that will display a PDF in browser without a plugin.
You might consider embedding an IFrame that points to the PDF in a lightbox style. That's about the best you'll be able to do, though.
To sum up your options:
If a screen-shot of a portion of the PDF is good enough, then as tomlog answered, you could find a library or existing code to extract said portion as an image, and display that image in the "lightbox".
If, however, you need actual PDF-viewing functionality, it can not be done in IE6/7 without loading into an Adobe Flash/swf object, or contained within the official Adobe Reader browser plug-in somehow.
Going the plug-in route, you will have to use an iFrame.
If the Flash/embedding approach seems better, jvenema suggested http://stickmanlabs.com/lightwindow/ which has a "Flash Paper" demo (Flash Paper is the official way to embed PDF documents) you could check out, or embedding something else, as seen at http://www.scribd.com/ and others.
artViper's bumpbox
Bumpbox 2.0 a lightbox clone with support for PDF, flv, swf, audio, images, inline HTML and remote html files. Now also plays
Youtube© & Vimeo© videos directly out of the box!
If it's not here, it's not anywhere: lightbox clones
You have a couple of solutions here
You could embed the PDF in an iframe (in a lightbox or panel) like http://www.cs.tut.fi/~jkorpela/html/iframe-pdf.html
Otherwise you could upload the PDF to a document sharing site like Issuu and embed their swf in your web page.
If you can find a PDF library that allows you to convert each page to an image (JPEG, GIF or something), then you could display those in your lightbox.
Obviously you would lose all the zooming and paging functionality of the PDF.
