So I keep trying to upload a megacomposite photo I made showing some routes on Bear Creek Spire. Every time I try to upload the photo, the upload screen uploads for awhile, then directs me to a blank page (except for the SP header & footer). I keep trying to upload this particular photo with no success.

Any thoughts?

Specs are: 4881x 5676 (9.56 MB)

If the problem is one of image size, I wonder what the best option is. The supercomposite isn't really useful if it is shrunken down :-/

Is it a jpeg? You can try reducing the quality a bit -- that will often reduce the file size.

Bingo. That did the trick!

"JPEGs, GIFs, and PNGs of any dimension are accepted, but they must be less than 8mb in file size."
