How are you trying to post photos? You can upload them to the forum, but you're limited to size, quality, etc. I host my photos on my website (I use Smugmug, but you can use free sites such as photobucket) and post links.
Click the yellow box above, the one with a little mountain and a moon in the corner, then post the link to the photo.
Copy the web link to your photo, then paste it into the box that pops up.
