Can ASP read picture width and heigh? I need it for upload script, if some one uploaded big picture (not in KB but in size!) to write error to user. I just need a script that will read picture width and heigh.

You would not be able to determine the picture size until you uploaded the picture using asp as asp is serverside. Now most upload components support a maxwidth property and some even resize it automatically for you. Check the component documentation.

like I said, what component for uploading are you using? That may make it much easier.

What if I don't use any component, like Pure ASPUpload? A file is then saved to a dir.

One can easily get the file size, last mod date and all that, but not the pixel dimension.

How can I get hold of the picture dimenssions?

Thx.
