use the square next to the star on the tool panel on ur left, the one thats made out of dots
pick it, choose the part of the image you want cut, press left mouse click and hold it down until you got what you want, release it and the square should still be there
copy it (CTRL+C) then go file > new and paste what you got copied, (CTRL+V) save it as jpeg and upload it to imageshack.us or tinypic.com like xenor said
save as .png to keep file quality, but file size low.
