When you click on links to various merchants on this site and make a purchase, this can result in this site earning a commission. Affiliate programs and affiliations include, but are not limited to, the eBay Partner Network.
Open the picture or pictures up in microsoft paint for instance or whatever program you have that will edit pictures and click "file" then "save as" and Underneath the name you can select format or you can just do example: "quad.jpg" in the name field. Hope that helps out.
