That makes sense.

Perhaps we can think about how to eliminate the angle and dimensions,
at least for images with EXIF data, where those could be populated on
the fly if/when needed (or in most cases, probably just done as a DB
query).  Those shrink my (compressed format) index.xml from 41 MB to
35 MB (from the original 53 MB).  I haven't measured the impact on
startup time; I'd SWAG that it will be around 5%.
