I am trying to list larger groups of chips on Ebay.

My images are smaller than I would like them to be. Sometime a listing will have the little magnifying glass that solves the problem, other times it does not appear and it will leave viewers in the dark.

What can I go to make the mag. glass appear all the time. Here are the images I have posted so far. Thanks for any and all help.
