I think variables for more than width and height might actually be a bit
redundant, since all the other variables are just copying over values from src,
which are known values when the tag is being created, that won't change on
their own. A developer could just type them a second time and be done with it.
This doesn't prevent the width and height variables from being used as part of
a folder structure or filename either. Trying to use a something like
{filename} could also cause problems if you want to use
src="img/blog/anImage_200x300.jpg" as your fallback, unless the variable can
strip the sizes out on it's own.
