Hi there and welcome to RayWiki.
About the thumbnails, it's a known issue that's been going for a while, best way is to watch for Hunchman801 to apply a temporary fix on each pic that's been recently uploaded. He;s currently looking for a permanent solution. --

Welcome to RayWiki, Zutheskunk! Don't worry about resized images, they usually get fixed very quickly.
I also see you're from Poland, do not hesitate to contact me if you're interested in a Polish version of RayWiki.
Thanks for joining anyway!
