content: Use whatever you're comfortable with; this is just one alternative. The benefits of this little program is that it is 1) extremely easy to use - GIMP is most definitely not, 2) it is also open source, and the source code for this one is just a few hundred lines (if that..), you can review it yourself in 5 minutes (good luck doing a code review of GIMPs millions of LOC) and 3) it is sufficient to get the job done. Installing GIMP for the sole purpose of stripping image metadata is a bit like starting a logistics company an buying a fleet of 18-wheelers to pick up your groceries.
