Here is an offending image: https://i.imgur.com/nqkq8PO.jpg I was not sure if that's https://github.com/Roughsketch/imagesize/issues/2, so I filled this new issue.

P.S. Thank you for the great software!

I took a look at it and it seems to be an issue with the way JPEGs were parsed. There were multiple sections in that image with FF FF <tag>, but the first FF would cause it to skip the actual tag since FF FF isn't a tag. This should be fixed now.

I also went ahead and ran a test on every image in my pictures directory and found one more JPEG related bug which is also fixed. I'll push 0.8.2 here soon.
