Gallery question - am I dumb?
Jan 29, 2014

Hi there.  I just can't figure something out about uploading a picture to My Gallery here in DPReview.  The maximum upload size is specified at no more than 20 mb, with a maximum of 30,000 pixels along any axis.

I shoot with a 5DIII, at a default aspect ratio of 3:2.  That's 5,760 pixels by 3,840 pixels.

I'm trying to upload a few pictures, and I've exported them to a file size of roughly 4 mb - so the 20 mb limit certainly isn't being exceeded.  However, I'm getting a "file is too large" error message.  How can that be?

Is "axis" defined as any edge of the picture? If so, the greatest amount of pixels along any edge in an uncropped picture out of my 5DIII is 5,760, well below the 30,000 pixel limit.  What am I missing here??
