Re:
mosaic thing.
Try this. (Give it a line-break list of journals and it should produce the code for a five column table of their default icons, in the order they were given.)
(LOL terrible code is terrible. I should probably add proper input handling and make sure you can't SQL injection attack it.)
ETA: note, requests are cached. Changing default icons will not get noticed until I write the bit that checks the cache timestamp and does a refresh.
