Ascii-o-Matic is a Flash application that reads your JPG image and creates an interesting plain text portrait filled with just ASCII characters [like you see in the example above, the picture in the inset is the original image]
You also get an HTML version of the image meaning you can copy-paste that code on any webpage. Or just save the generated ASCII image as a standard graphic using any screen-capture tool.
ASCII-o-Matic is faster than most other ASCII conversion tools out there but you are limited to uploaded only JPEG images with a standard 60x50 size.
ASCII-O-Matic.com - probably a good place to convert those MyBlogLog Avatars into text images.
