Welcome to Beesource!
Posting photos directly using forum tools can be a pain. The easiest solution for some of us is to post them to a photo host and then link to them in your Beesource post.
An easy solution is to open a free http://photobucket.com/ account, upload your photos to that site, and then link them here.
If you want a step-by-step guide to using Photobucket with Beesource, see post #8 of this thread:
The thread linked above is a guide for posting links that the reader needs to click on. You can also post photos inline that display with the text. Photobucket calls that "Direct", and then you need to use the "Insert Image" button on the Beesource message toolbar. Choose the URL tab, un-click the box and paste the link.
