Click "Browse".
Find image on PC.
Click "Host it".
Repeat as required.

Incidentally, you've been told before about double posting. If you think the whole world is going to respond to you inside 20 minutes, your expectations are set a little too high. Just because you've had no response in 20 minutes there is no excuse to post "anyone?" - your thread is still at the top of the forum anyway, bumping it is completely unnecessary.
