P.S. EVERY time this topic comes up someone is confused on how to do this. Here is the step by step:
1 | Hit [PrintScrn] button (next to F12)
2 | Open a program such as Photoshop, MS Paint, Paint Shop Pro etc. and hit either [Ctrl+V] or Paste.
3 | Save image as a .jpg
4 | Either create account or go to account on a server (IMHO
www.fototime.com is most reliable, webshots does not seem to work anymore)
5 | After picture is uploaded, right click on picture in album and select "Properties"
6 | Highlight entire URL and copy it
7 | Come to this fine thread and type [img] then paste the url followed by [-img], replacing - with /.
HTH
