I try to remember to warn people to save siggys I make to their computer and uplaod them (but a lot of times I am in a hurry and forget).

That is the FIRST thing you should do when someone makes one for you since when you make siggies a lot, you have a lot of pictures uploaded and every now and then, I go in and delete a bunch of the old ones (and off my computer also). Please remember to save to your computer and upload to your own online storage to be sure you have it and that will save a lot of confusion when we go in and clean up our online storage..

It could be that the picture is just not avaliable in PB right now and show up on it's own shortly because of maintance or something.
