Comment (by [EMAIL PROTECTED]):
About your worries, the width and height values are updated every time the
imagefield save method is fired, they could only be out of sync from a bug
or a wrong use of the FileStorage mechanism (like setting the ._name field
attr manually).
Also I have been using the patch I submit and has been working fine for
me.
Without this patch the people that use remote filestorage backends (like
S3, nirvanix or mogilefs), suffer a big performance hit for having to load
the entire file every time a Model with an imagefield gets loaded. That
means in this scenario a lot of more traffic, less performance and also a
monetary cost.
English is not my primary language, sorry if something is not clear.
PD: im attaching another patch that could be more safe.
