Upload script should only look at files that match filetype in config.ini

The iteration loop here grabs all files and attempt to extract height and width without checking to see if the file is actually an image.

This could probably be done by replacing subfolder.iterdir() with subfolder.rglob(filetype). Shouldn't be too hard to do, but I don't want to create new errors. Could @olgaliak or someone else try changing this on their branch and seeing if it works?

@yashpande I know. Just logging the bug so we will fix. Most likely will rewrite this area.
