I've been experimenting with the various ways to link to photos in Twitter.
This is a photo I recently upload to Flickr. This works well for blogging since I can create a blog post right in Flickr. I want to do the same thing for Twitter.
TwitPic allows you to upload and create a Tweet for Twitter. It's easy enough to do but they seem to overcompress the pictures they host, so much that the compression artifacts are a little offputting.
