I was on a website earlier in which I wanted to submit a receipt. The types of files in which the receipt can be submitted are these: jpg, gif, png, xls, xlsx, doc, docx o pdf. I used to be able to submit it to them via cut/copy/paste. When I click "Choose File", I get the on-screen message, "selecting files not supported...". Is there an application with which a receipt can be submitted using one of these supported file types?
