I personally don't care if there's another site (or a dozen for that matter) on the Web to publish screenshots. More power to them. I've simply sat here and heard people tell me repeatedly about non-existent limits and what I consider complaints about our own screenshot gallery.
For the record, having just checked, the limits are 1600 x 1200 and 300kb. The images are NOT resized, though if the people complaining had any concept of what they were talking about, they would know that when we upgraded the module about 6 months ago, there was an accident that resized all images automatically. Nothing I can do about that, or I would have.
