What's the best way to post nice, high res images to the forum for a TR?

I kind of hate the native TGR image attachment thing. I used to use imgur, but none of the images in my last TR show up anymore. Photobucket has also been funky lately with watermarks, pay to play, etc.

So what's left? When looking at some of the better photos, I see smugmug and flickr. Other thoughts?
