Reply To: I've set myself a challenge.

Hi Butterfly, Flickr is the one that we mainly support because we also have a morsbags group with many members on it. You should be able to use any site where you can store photographs as Beattie mentions like Picassa, Photobucket, as long as you can paste a link directly to the actual image url (e.g. the link should end in .png .jpg .jpeg .gif etc and is not the page that has the image on and a lot of other stuff around it) then all you do is highlight the URL you pasted and click ‘img’ above where you are typing into and it should work.
This forum supports Flickr a little better and all you have to do is paste the link to the photo page and it should do all the clever stuff to get the direct photo link (no need for highlighting and img tags etc)
