Posting images in threads??

Is the only way to post an image or schematic clipping to a forum post by doing an image upload??

Is it not possible to use a cut/paste utility to paste an image or screen clipping directly?

I use (and recommend) a little utility called Faststone capture (from www.faststone.org) which allows one to capture a snippet of a screen shot (or the whole screen) to the clipboard (or a file) and I would like to be able to just paste from the clipboard to the forum without having to first save it as a separate file first.
