How do you get such nice pictures uploaded when the limit is 5K? It won't take any picture I try to upload.
I use ImageShack (www.imageshack.com).
The GDC gallery is worthless because of its storage limits.
You can see what people are using by right-clicking the photo and inspecting the Properties option. I like www.tinypic.com.
Simple, bare bones, no fuss. Just go to there and upload. Only for shots 250k and less, which is no problem for this type of posting.
You do have to keep a record of your posts, since the site provides no dedicated space for your stuff.
