I did take a peek at that Image->Table converter posted by bastard, and it is remarkably similar to my own. 'course using GD instead of parsing it yourself is the easy way out. ;-)
The thing that I find most comical is that I actually developed my HTML-izer for the very same reason that bastard did: to get around the restriction on posting images for low ranking monks. I decided that the files were prohibitively too large to actually do it, mind you.
So I definitely think that "parallel evolution" is the appropriate name for it.
