There are a couple ways to insert an image into this forum, but here is the easiest:

First login and upload your image to the photo gallery. Visit the image page where you will find the fields "URL:" and "Embed:" on the right hand side. Copy the "Embed:" information. You can do this by highlighting and right clicking and selecting or by using the Ctrl and C button. (Macs can be different, but if you use a Mac I am betting you know the shortcuts ;) Now post a reply or open a thread in this forum, hit the "html" button in the forum editor (by the blue question mark) and new window will open up. Paste the code in (ctrl V or right click or just type it in).  Click "Update" and your picture should be in the post.  I have included an example to  prove it is possible!
