Subject: m.images: don't fail if Pillow is not available.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~cjwatson/git?a=commitdiff_plain;h=0bdd5845b52da7043948824938ac6a589851f48f;p=blog.git

m.images: don't fail if Pillow is not available.

It should be possible to use the plugin even w/o Pillow (but then image
grid won't work).
