Notice: Twitpic recently changed their API, breaking the module. I have not yet had time to fix it, but patches from anyone are welcome.
This module allows Twitpic images to be displayed directly on a Drupal site, allowing Twitter and Twitpic to be used as a mobile engine for a photo-rich blog.
Twitpic allows images to be posted to Twitter, appearing as URLs in a Twitter feed. Pulling Twitter feeds into Drupal is a great way to get easy mobile micro-blogging, and some mobile Twitter apps include photo upload capability.
The problem is that the feed only shows URLs, not the images. The Twitpic API allows thumbnails to be displayed in a browser, but makes the full images available only as downloadable files. This module uses an Input Filter to intercept Twitpic URLs, download their originals to the Drupal filesystem, and display the images instead of the URLs to the end user.
