One suggestion OP - since you've run into the Int32 issue with several popular images (which are showing downwards as well as flat lines), it's probably worth defaulting to less 'faulty' image with upward slopes, or perhaps a random image from a curated set to showcase some actual growth.
It's a shame the issue has languished, it would be interesting to see just how many times nginx was actually downloaded.
I noticed your `www.` URL doesn't work (times out) but it works without. Your README links to the www version.
