That's right, getimagesize() needs a file. But if you need to, it
shouldn't be hard to pull the image out of the database into a temp file
and do whatever you want with it.
Not that that is necessarily a good idea (for reasons of security,
performance, etc you may not want to introduce an extra database query
or an extra temp file). There may be better ways to do what you want.
But it is possible.
You can also use a URL with getimagesize - so you could call the CMS'
retrieval script via HTTP and make it do the work for you.
