Image accessibility

[marnanel]

I have an accessibility idea. I shall probably do it, unless it turns out to be fundamentally flawed. Your thoughts are appreciated!

1) A site that takes an uploaded JPEG, and a string, and returns the JPEG with the EXIF comment field set to that string.

2) Browser extensions for Firefox and Chrome which set the alt property of each JPEG on a page to its comment field, if it has one.

This means you can describe an image before you post it, and that description travels with the image. Thoughts?

Nitpicks: do you mean alt, or title, or both? And does an alt-text or title-text provided in an HTML img tag override the one pulled out of the JPEG referred to?

How many sites of the like of Twitter/FB/Tumblr actually preserve exif across their various resizings, resamplings, and adding JPEG artifacts?
