Can I upload an image or text file to ebay using an alias of the file?

Hi,

I don't want to make a lot of duplicates of my photos. I need to upload photos to eBay, Craigslist etc. Can I upload a file by choosing the alias of that file when I'm in the 'post photos' part of creating an auction?

Thanks,

Rafael

PS Soon I'll be working on Mountain Lion.
