yes, why don't you show us some of the code please.
off hand, if i understand right. depending on how many icons the script has to load, if it's many as you say then it's possible that it's getting bogged down because the script has to load and re-load each image. normaly that shouldn't be a issue (i don't think) but if you have multitudes of images to load, then it's possible thats what's going on. i could be wrong on this but, it is possible.
