Provide accessible text

[KatieK2]

Provide some sort of computer-readable text along with the image for accessibility purposes. This could take one of many forms:

• Server outputs a custom header in the request for the image. (Note that currently images are saved to imgur.)
• Metadata embedded in the .png file.
  Even if no sites or screen readers are currently searching for this data, we will give them a new data source from which to pull.

How about this for a quick and dirty solution:

• Have every Typeslab also tweet @alt_text_bot to attach a text description?

This could be cool actually! I would need to actually tweet the image from the app, though, which is a bit more complicated (I'd have to run a server & get post permissions from the user through oauth OR they'd only be able to upload a link to the IMGUR, which Twitter's apps wouldn't treat as an image)

Of course, if I did that, I have the input text anyway so I could tweet a reply from a dedicated account.

Alt-text embedded within an image would be really interesting and much easier (the image can be hosted anywhere). PNG does have TXT blocks but nothing reads them as far as I know.
