[spoiler]Support of "*https://portfolio.commishes.com/*":https://portfolio.commishes.com/ is dirty and incomplete: it does not providing *original file*. It doesn't even allow you to upload file directly right now. Right now it just grabs info about original dimensions and provides rendered thumbnail with mentioned resolution. +Result files should not be considered as original because of jpeg compression (even if script tries to provide as much quality, as possible).+

Expected size — in which size file was uploaded and original file dimensions.
JPEG size — multiplier for jpeg thumbnail. Bigger size should reduce jpeg artifacts but will result in longer processing.
HQ rescale — uses sharper downscale algoryth but works longer.[/spoiler]
