Thanks guys, how weird! maybe it which link you choose to put in as it offers a few, as in direct/image etc. I THINK I use direct.
OK, so having said that I thought I’d do a little experiment to see! 4 (hopefully) photo’s will show here - I’ll do the links as they are in order on the site - lets see if we get watermarks.
There are pics under all 4 numbers, wether you see them or not is a different matter, all are at 30%

1. email/im

2. Direct

3.HTML
!!
4.IMG

There that’s all 4, the HTML one always seems to work, be bigger and have a bit of code tagged to the end - but I can’t see watermarks on any, just the last not working one, and the first one that doesn’t display anything.
Why this is doing this to some users and not others is very strange!
