That is now available on the SXM and BVI and Testing forums. Will roll it out across other forums probably during the week.

It works similar to the photo gallery as far as uploading your photos.

They will display as thumbnails at the bottom of your post. If you click on the thumbnail it will open up a slideshow of your photos. You can also link within you post, extra step, meaning that you will have to edit your post after the photos are uploaded. In that particular case it is probably easier to create the photo gallery first then link. But the option is yours to choose how you want to do it.
