snapshot - 512x512 or 512x256 only

I am having an issue with taking snapshots. For some reason, no matter what I have the settings on, all I can get is a 512x512 or a 512x256 size picture. I have a wide screen monitor, so the 512x512 looks squished. I use Nvidia 8800 GTS cards, don't know if that makes any difference. The snapshot feature worked just fine before they changed it. Anyone have any ideas?

Nothing has really changed, other than I think they capped the maximum upload size. No matter what, you are going to get a squished image off a wide screen resolution, what doesn't help matters is they broke the ability to view snapshots in any aspect ratio where you could stretch the image (both horizontally and vertically) on your screen to view it better, now it's locked square. I've found the best thing to do is just slap the image on a prim and stretch it out that way.

That's what I've been doing, just a pain to have to do that when I could just stretch it out before.

Assuming you are trying to upload a screen capture taken ingame from your HD, have you tried using the High Resolution screenshot 'feature' found in the Client menu? Also, even with a widescreen monitor, you need to check the screen resolution of the client matches that of your default desktop in preferences.
