Once you get the image url, do this:
http://prntscr.com/8dxh2.
The link should show up in your chatbox with "[ IMG ]" and "[ /IMG ]" around it. Copy and paste the whole thing and do this:
http://prntscr.com/8dxng
Sure, I didn't explain it well, but I THINK you get it?
Also put the image link on the bottom and the regular link (where the image leads to) on the top.
