TinyPic/IMGUR are great image hosts. Your STEAM screenshots are saved on the HD you just need to right click your STEAM toolbar icon go to screenshots and find the show on disc option to get access to the folder.
Then it is a simply a case of copying them elsewhere and uploading them with TinyPic/IMGUR and showing them off much easier on the forums .
Photobucket is another great one
makes it easier to embed them in the forums so that we don't need to click on links because we're all lazy, I mean come on, we're on the internet for goodness sake! XD
I'm afraid those links wouldn't load for me, but I'm looking forward to seeing what you're new textures look like!
