true starlock the other sites I go do have different size limits and most I do go on don't require a size limit which is good in ways.. anyway to answer your question Iv'e resized them to look bigger when you click on them because My scanner is not working at the moment so I'm might to looking to buy a new one and the reason I made them bigger is that they stand out more because without a scanner the attachments look quite small without a scanner so that's one of the reasons why but It's no problem I can rezize them anytime I want to thre proper requiements 500x150.
