blurring out or display half of the content of the pdf file

Is there a way to blur out the contents in pdf programmatically? If not blur, just display the 3 pages out of 10 when users view the pdf. I am making a program where users can view the page, but only the tip of it... like the table of contents, if they are interested on it they can request to the admin for file download.
What I've search was redacted pdf, which I manually need to save the file. The pdf file have like 10 pages up.
If it's possible that this can be done through php/js. I don't have any code yet since I am trying to search for some ideas but nothing shows up.
Similar Function: It's like something like the pay per view of some websites, when you are reading there's like a notice that you need to pay to read the whole pdf.

Set Button icon using attached file

I'm creating a kind of template for users to fill out in Adobe Acrobat Pro X, but they also need to attach photos. I've created a button based on this thread here which, when clicked, prompts the user to select a file and then attaches the file to the PDF. It works beautifully, except the template pdf has multiple pages with multiple locations for photos.
I need a way to keep track of which (picture) attachment belongs to which location. My main idea so far is to simply insert code that will take the file and use it as the button's icon. (This is also good in the case where the user accidentally attaches the wrong file, then goes and uploads the right one without deleting the old one; I'll see the most recent choice and assume it's the correct one).
The other idea would be to rename the files as they get attached (to Attachment1, etc.) but this doesn't seem to be as feasible.
There are 2 different functions for the button depending on if the users are using Reader 11 or not.
When they are not using Reader, the main code looks like this:
app.alert({
cMsg: "Please select a file to attach.",
cTitle: "Attach File",
nIcon: 3,
nType: 0
});
try {
var rc = this.importDataObject("Attachment" + attachment_num);
if (rc) {
attachment_num += 1;
app.alert({
cMsg: "Attachment successful.",
cTitle: "Attachment Successful",
nIcon: 3,
nType: 0
});
I was thinking as the first line of the if statement, I could insert code to change the icon of the button that this code is running from, but I can't figure out the right thing to try. I was looking at using buttonSetIcon based on here but I'm doing something wrong, probably because of my lack of JavaScript knowledge.
What I was trying was something along the lines of this
var f = this.getField("ImageButton");
f.buttonSetIcon(rc);
It doesn't work though. I am not sure what exactly importDataObject returns in the variable rc but I was hoping it would be the file itself.
When the user is using Reader 11, this gets even more confusing because everything seems to just be one line of code, annot.cAttachmentPath;, but I'll focus on the other version first.
Any ideas?

Put the following line of code in the Mouse Up action of the button.
event.target.buttonImportIcon();
This will open a file selection dialog where the user can select the image to import and set it as the "normal" button icon. It will import the icon into the button that was pressed so you can use it for multiple buttons.
Note that in Reader, the image will need to be converted to PDF first. In Acrobat, the conversion will be automatic.
If you need a way to add images (as images) to Reader and you can tolerate the user positioning them manually, you can simply paste the image from the clipboard and it will show up in the PDF as a stamp. You need to instruct the user on how to get the image onto the clipboard though. Then they need to scale and position the image.

How do I automate my workflow with Javascript to save bunch of images

I am trying to copy paste some stuff from some website which I want to automate. Here is my manual workflow:
There is a master webpage which contains set of links.
When I click on one of those links it opens another (say topic page) page with set of tabs.
I click on one specific of those tabs which loads a page containing several buttons with same html-css applied to them.
On click events of those botton calls a javascript function passing four integer parameters.
The function results in generating a separate popup window with some small content which I then print as pdf.
The issue is that the website blocks right click and text selection. And the popup window contains a image which I print as pdf by right clicking on titlebar and selecting print as pdf. When I checked the source of popup, I found that it uses
"data:image/png;base64,<source for image>"
as value for src of <image>.
Now the big question can I write some script which can run when either master page or topic page to automatically click on buttons on them and get those images saved either directly as png or pdfs? I am good at programming languages java, groovy, python, C#... Also explored javascript a lot. But that's many years ago and really lost in touch with JS. Can I do this with say greasemonkey or any other way. Any pointers (possibly detailed) will be helpful...Or even some small pseudocode which I can paste in console of topic page which will do all clicking of buttons and saving image from the popup, so that I don't have to do button-clicking-&-saving-image manually. This will also serve a lot since there are more buttons per topic page instead of number of topic pages themselves.
Update
Well I know this question is not at all specific, so here is my initial hurdles, since I have started to try it out:
given that I am programmatically call all those function on onclick events, how can I get hold of popups in source? That is, how can I reference the popup that is opened by function call in js?

Is it possible to get the "download" link for a file request to a server (I guess it's a server) in javascript?

I have this Fund family called Fidelity which I have to update monthly. It has ~250 funds on it's page.
E.g.: https://fundresearch.fidelity.com/mutual-funds/summary/316345206
On each I have to click on Prospectus & Reports, it will pop up a window, but my download will only start if I click on the Monthly Report button:
When I check the link for this single download it gives me this: https://www.actionsxchangerepository.fidelity.com/ShowDocument/ComplianceEnvelope.htm?_fax=-18%2342%23-61%23-110%23114%2378%23117%2320%23-1%2396%2339%23-62%23-21%2386%23-100%2337%2316%2335%23-68%2391%23-66%2354%23103%23-16%2369%23-30%2358%23-20%2376%23-84%23-11%23-87%230%23-50%23-20%23-92%23-98%23-116%23-28%2358%23-38%23-43%23-39%23-42%23-96%23-88%2388%23-45%23-88%2316%239%239%23104%23-128%23-21%23-39%23-74%235%23-89%23-105%23-67%23126%2377%23-126%23100%2345%23-44%23-73%23-15%238%23-21%23-37%23-17%23-14%23-98%23123%23-18%2345%23-59%23-82%2367%2383%23112%2317%2370%23-78%2378%23-50%2336%23-86%23-90%2381%23-21%23-119%23-30%23120%2349%2328%23-98%2333%2351%23-78%23-119%23-16%2350%23-58%2350%23102%2348%23-17%2352%23-99%23#
This changes monthly and this will only get me to this report, not to the latest one available.
But with these links I can't really recognise the changing part and it's logic.
My problem is that I am not really into javascript and can't really see the whole process that goes down on the site when I click on the button.
P.S.: The download comes w/o a file extension, but giving them all in Total Commander is the least of my worries. Let me know if you need any further details.
Is there any way I could save ~1500 clicks and a half day?
If there is any part which is not clear, let me know and I will elaborate.

Interim message when downloading a file

On my website I have an option to display some data and also to download it in csv format. Some of the data is quite large (20,000 - 900,000 rows in SQL). When I display it on the site I use paging so that it quickly displays only x amount of rows at a time, however, the download link of course should and is downloading the entire report which can take several seconds to a couple of minutes depending on file size. I'm wondering if there is a way to create an interim pop-up or message in-line that says something like "Gathering Information..." where I could additionally put an animated gif so the user knows something is happening. Creating this shouldn't be an issue but I'm not sure if there is a way to trigger that to disappear once the download pop-up appears. The solutions I've seen on this site all suggest using a timer, but thats not an option in this case as the times will vary a lot.
I'm using classic ASP so would like to use either that or JavaScipt. I could additionally use flash if makes a difference.

I would probably wire up the "Gathering info..." message to be hidden upon receipt of a Comet style message from the server that could be sent out as soon as the file is ready to download on its end.

The gist of it is to use a cookie that you set using pure javascript or jquery cookies for ease of use. Then you send the cookie's name to your server, which sends an update for said cookie with the file once delivered.
Meanwhile you have some JS code that checks periodically for the cookie to see if its updated, and can then update the layout accordingly.

I ended up doing this a different way. On my site I have page we'll call "default.asp" on that page is a link to another asp wel'll call "download.asp". download.asp is where the code is to do the SQL query and create the report, which means this is where the wait comes in. After the report is prepared the popup to save, open, etc is displayed. What I ended up doing is creating a div that by default is hidden. When the download button is clicked the div is unhidden, then just before the popup is displayed I once again hide the div. Hopefully this can be of help to someone else as well.
