You can use the GetFileDimensions method of Shotgraph component:
http://www.shotgraph.com
It returns both image type and dimensions.

1. Define 'image size'. Do you want width and height or file size?
2. Do you want this from the local drive, i.e. with ASP Upload prior to
upload, or do you want it from an image on the server?

I can get the file size, width, and height either from local or server
without components and without using FSO.
Please advise.

How do you manage that then? I would have assumed you'd need to use the FSO
to get information about a file.

On the server-side you do if it is not an image file. If it is an image
file you can create a new image and set the src to your image file. You
then can use fileSize but there is an issue. When I do it quickly, it
displays -1 for fileSize. If I introduce a delay, it works.

This is one I wrote that allows you to check the file size and image size
(width/height) before you upload. It has a flaw because it will not clear
the file upload text if the file fails validation so I'm using an
alternative method for submitting the form with valid files. I got a
response from HikksNotAtHome about using a dummy form but I have not put in
his method with this code yet.
