I made a logo with my Xara3d5 and i was trying to put it on a website... however the website used in Postimage.com used to load pics onto the website will not let me upload my logo onto the website. It only supports .gif, .jpg, and .bmp files. When I try and upload the file it says "Invalid file type." So I was wondering if there was any way to convert the file to one of those file types. Is this possible?
