[feature request] automatic image processing after upload

[retrogamer1337]

I collect videogames and use koillection as a database for my collection. I add around 1 to 5 images of the games to each item. For now I have to process the images (taken with my phone = 2-4MB each) with birme.net (image processing batch tool) to make them a pretty usable 50-200KB bevor uploading them.

It would be awesome to specify some values for each collection like (image-filetype, target width/hight, target JPEG Quality) and then just throw everything in it and let koillection make the rest automaticly on its own.
