Image Syndication and Weblogs
Basically, the idea has two parts: publishing images using RSS and a search tool to find images related to whatever you're working on. Don says, "Tie two parts together and you got something neat. Imagine writing a post about Bill Gate and being presented with a selection of Bill Gate pictures including one taken this morning by himself. Cool!" Yup, that's pretty cool.
The biggest problem I can think of is getting good metadata about the images. Otherwise you can't search on them very well.
Don seems pretty busy, but maybe someone will have time to make this happen.
