Abers... I had the same problems at first...
Grab a photos URL... right click it... code looks like this :
http://farm5.static.flickr.com/4010/...4597426c_b.jpg
copy that...
click the symbol above that looks like a mountain...
Paste the URL... and make sure it says this [IMG] [/IMG] at the beginning and end of the code, and not url [/url]... there really should be an easier way of doing this now!
That should hopefully work for you : )
Beauxreflets, nice shot : )
