Or you could post them in the gallery. Go to the top of the page and hit "Photo Gallery", from there pick "Upload Photos" on the left.
When the new page launches select the correct category (which I assume would be down towards the bottom - Members FW
Use the browse button to find the file you want to send then hit submit
(there are limits on the bottom of the upload page that you should read to make sure your photos are w/in the parameters)
Once posted one of the mods will approve the photos at which time they will be visible.
If you want to post the pics in a topic you can go to the photo in the gallery, copy the URL and paste it into the body of the message.
Looking foward to your photos
