That is correct Rob. I was looking back through your posts to find one where you had uploaded a picture without success to see who you were using as host.
One tip is that Dropbox is useless for use with forum software for photos. Files seem fine but photos drag the whole thing to a crawl which annoys all the users.
Most of us here seem to use Photobucket and that seems to work well by having two windows open when composing a message and simply pasting in the img tags. Their software could be a bit more user friendly but it interacts with PHPBB very well when topics are being read which is where it matters.
I think Flickr is also quite good but never used it. Mike G uses IMGUR I think and that is also fine from a readers perspective.
