Hello Curtis and the others,

This is exactly what I needed. I am doing some testing with images,
etc. My plan is to read/check a
given image file, and load its name, size, filetype, etc into a
database, and display the image (via a thumbnail link, etc). So the
link to the php stuff is very useful, and all i need at this point is
to get image data, and do not need to process image yet (like make a
thumbnail, resize image to browser size (maybe 900 x 600, etc).

Thanks again,

eholz1,
