I use my IPhone to read the forums and comments. Can someone tell me how to post before/after pictures?

It's tough to do from the app. You can do it but by clicking here. That'll open your browser. You'll need to scroll all the way to the bottom of the page and click "FULL VERSION". That'll bring you to a page where you can upload your before and after pics. I suggest trying this from your desktop computer instead.

I do it from the app by clicking on the Advanced tab on the right of the post. From there, it gives you an option to attach a picture from the camera.

Like so. See the advanced tab to the right? I get this when I hit reply to a post or when I start a post.
