If someone explained to me how to add a photo, I have one to add. (I have an iMac, and I have a hunch the 'Insert Image' only works on a PC).

I have imacs and easy to add a photo

- slide your photo from iphoto over to onto the desktop
- then do a post
- select additional options
- the select browse > desktop > select photo (but needs to be under 2mb)
- if your photo is over 2mb on the desktop open it > duplicate > save as and adjust the file size

hope that helps
