I think the gallery size limits are way over the top and should be reduced. I open some of them and have to scroll left to right and up and down to see them. I'm on DSL and some take time to open as well. I render in 800 x 800 and optimize the file to a reasonable size. I think that's plenty big enough for an online gallery.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
