Importing images in bulk in Acrobat - javascript

I have a listbox in an Adobe Acrobat form. When I change the value of the listbox, the source of the image field is changed with a javascript script. See question

Is it possible to add these images in bulk, so I don't have to add them all (80 images) manually in the PDF file?

Limit document type for file upload box in web form?

Is there a way to set what file format types/filters through HTML or JavaScript?
I want the user to be able to select when he clicks the browse button on a web form. For example, I want to give him the option to select only JPG, GIF and PNG files for upload.
I know this is possible in Flash.
See input, accept (HTML element):
accept
If the value of the type attribute is file, this attribute
indicates the types of files that the server accepts; otherwise it is
ignored. The value must be a comma-separated list of unique content
type specifiers:
A valid MIME type with no extensions
audio/* representing sound files HTML5
video/* representing video files HTML5
image/* representing image files HTML5
Or see example here.
