Image Resolution?

Percadan

Can anyone provide some direction, besides a link to the gdlibrary, on displaying image resolution?

I would appreciate it greatly!!

Thanks

getimagesize() doesn't require GD.

You're correct, but that function only returns width and hieght.
I am looking for dpi resolution; i.e. 75dpi and 300dpi

Thanks though!!

Oh right .. well .. for GIF and PNG files there is no dpi value stored. For JPEG the value might be stored in the EXIF information .. but it's not very common unless the jpg came from a digital camera. Try http://uk.php.net/manual/en/function.exif-read-data.php .. but I wouldn't be too hopeful.
