Alnum photos can be inserted in the MP3 ID3v2 tags, and are viewable at least in Windows Media Player, iTunes, ...

There's no way to stop downloading it because it is part of the file content. LimeWire shares files, not fractions of files. LimeWire does not parse files to determine which part is useful and which is not. Instead it parses MP3 to get its embedded meta-data in ID3 (and now ID3v2) tags, that help improving searches by keywords...
