Judging from the description of the software, it seems like this could
fit in gnu/packages/image.scm.

The same effect is more directly (IMO) accomplished using the following:

(string-join (string-split version #\.) "")

Nitpicking again: why the double space between "description" and the
double quote?

Also, the linter says that this package vulnerable to
CVE-2015-8979. Supposedly this* upstream patch fixes it. Could you see
if that fix works for this package?

Other than the above, LGTM.
