Posting Pix on the forums.
Found a photo you like on the web and wanna post it on here?
If you wanted to link something from the web, lets say a pic of a walrus you would do this:
Google image search walrus.
Select the image you like.
Right
click the pic. Select "copy image location" (if using Firefox). Then
paste that into that "insert image field on this site". Like so:
If
your using Internet Explorer, right click, select "properties" and then
cut and paste the test in the "address:" area. Then dump that into the
"insert image" field on this site. Like so:
And actaully, if your using IE, you can just right click, hit "copy" and then just go back to the message area here on the forums and copy, right click, and hit "paste". And boom. Mo Walrus. 
Alternatively you
can "attach" pix of of your hard drive. Tha should be in the lower
left hand of the posting page. Simple find the file and it will load and then imbed it in your post (though you may not see the image until you actually "submit topic/post".
