Image uploads

[Matthias Bauer]

Hi there,

I know the question is a little offtopic, but maybe somebody can provide a quick 
answer anyway.

I want to upload an image file with struts (this works well already). But before 
storing the image in the database I want to check the width and height and the 
type of the image (e. g. gif or jpg). Does anybody have an idea how I can easily 
do this in Java?

Thanks,
