This project contains (among others) a module that synchronizes a specific Google Photos album with a local server. The code performing this synchronization had (maybe still has) some issues and I occasionally ended up with corrupted (partially downloaded) images.
Picking these corrupted images out by hand wasn't an option so I asked Google:
Is there a tool to check the file integrity of a series of images?
You bet there is ... Google answered ... and pointed me to jpeginfo.
You can either clone the repo and compile it yourself ...
$ git clone https://github.com/tjko/jpeginfo.git
... or just install it, which is what I did.
apt-get install jpeginfo
Run the check
I does exactly the job I needed it for. Navigate into the directory where the potentially corrupted images are stored and run the tool with the -c (check) option.
$ jpeginfo -c * ...

A couple of [WARNING] entries appear. These are the corrupted files.
So let's get rid of them (and assume that synchronization will work next time).
Run the tool again with the "delete all" option (-d -mall).
$ jpeginfo -c - d -mall *
All done. Next time I need this, I can just look up my own blog post.
