8 Value Ed - Hi Robert, I also use a Mac for my own build thread updates in the Sammio forum.
Unfortunately, I don't have my own website, so I've put my photos on PhotoBucket & Google+.
However, my Mac tips are as follows (apologies if you've cracked this now):
Hover the mouse pointer/arrow over any photo that is hosted on the web.
Hold down the "ctrl" key and click the mouse.
Select/Click on "Copy Image Address".
Then switch to "TextEdit".
Select "Edit".
Select "Paste and match style".
The photo URL should then be sitting there ready to add the img tags before and after.
Personally I prepare my posts in TextEdit and add the forum codes I need before copying and pasting into the "Reply" box on here.
This allows me to quickly copy & paste the img tags to multiple photo URLs.
( Note: The maximum number of photos/smilies you can use in a single post is 20. )
You can use the "Preview" option to check everything looks OK before posting.
It also means that you will not lose a post that has taken you a while to prepare.
Hope this both makes sense and helps a bit, cheers, Paul.
PS
Using the above technique I could copy the photo

Note: Forum automatically turns the URL into a link, but you get the idea.
