Earlier today I was checking the source of post #170117 and trying to see if any other images from the same site were posted. When I did a source search (up to the end of the "HealingPotion" part of the URL), I couldn't even turn up that image, which confused me at first. When I played around with source searching a bit, I found it only worked when I ignored the capital "H" and "P" entirely (like doing a search with "Source:*ealing") Not sure if this was ever brought up here before (may be old news - I just don't remember seeing anything about it) but it could be a bit of a problem with some URL's. Doesn't matter much in this case because it appears the artist moved to a different site. I did try the "Find Artist" feature after I had entered the information into the artist wiki, and it seems to work just fine and doesn't have a problem with capitals in the URL.
