I think that when you use the "search by members/artist's name" function you may find that you are not actually going to any one's particular gallery, but rather all the posts related to that search name, that includes any of your pics that the person you did the search on has commented on. The same thing happens when you do a search on your name, this is why the images you have commented on come up as well. At least I think that is what is happening! ;-)>
