Here's what I've found that works for me.

1. go to "photobucket.com" and get a free account. You can pay 25 dollars and get the mack daddy version which will let you post some awesome qualiy photos if you want.

2. once you've uploaded you photo (s) there, then you open another web page, like this one. Post you message, but, "copy, paste" the picture to this page.

Note: all web sites have different requirements and at photobucket they have all three options for you.

Let me know if I can help you more.
