The plan right now is to include the Title and Description information in Snap.as (so we can incorporate those later), and then include the alt text in the posts themselves. But it might make sense to add "alt text" storage to Snap.as too. We can do that if it seems to make more sense.

Gotcha, thanks! Since the current site stores for images:

• Title (used both as hover text and as below-image caption)
• Description (appended to below-image caption)
• Alt text (yep, alt text)

This is really the base functionality needed to preserve captions in the migration, and store them alongside images. So right now, these will automatically turn into alt-text that displays in the Snap.as UI -- e.g. the "Share on Write.as" Markdown text here:

How does this look in practice in terms of caption below an image, hover text over an image, and alt-text for screen-reader access?

Basic API docs are now live here: https://developers.snap.as/docs/api/
