Sure, I have been doing it for a while. Procedure as follows:
1) Make your post without the picture.
2) Email me the photo. I will upload it onto my spot on Photopoint.com
This gives us a URL to use.
3) I will edit your post, adding the picture.
The easier alternative for you more experienced guys is to post it to your own photo hosting site (there are a few good ones out there) and then insert that URL into your post using the "IMAGE" function you find in the listed UBB Codes on the page just below the edit box where you are typing your own post.
