Does it automatically resize images for a thumbnail? If not, it might should be called “Kill Mobile Users Bandwidth Allocations” given the incredible pixel counts available these days.
Yes, it does, we never send the original, we "stream" web-optimized formats of the images. We did some tests pushing to 250 pictures of 25mpx each on a single page and both the load time and bandwidth were very acceptable.
We also discussed with some of our users doing gigapixel pictures and they did not report bandwidth issues, which is very encouraging.
