Tom I use Dropbox and Photobucket. When I click the share tag I get an option to "copy link to clipboard" then paste into where ever you want to post it.
Thanks Kev. I use Photobucket too, but the Google pictures thing is pretty cool, it stores all your pics with no limit on space and makes them easy to find.
For example, I uploaded over 4000 photos last night, this morning I wanted to find a particular one so I searched for 'man hat' and it retrieved all the pictures I have of men in hats.
It works with all sorts of commands, I searched 'Settee' and It found about 30 pics containing settees.
It would be great if I could just post pictures to the forum from it using my phone.
