It would be very helpful if you could allow .gif filetypes and .pdf filetypes to be uploaded as a custom image. I know places like VistaPrint allow .pdf's and .gif's (of course, no animated gifs).
I would appreciate you looking into this and maybe adding it in a future update.
I would find useful to expand filetypes, gifs would be a great option
