How can I obtain the height and width of an uploaded image?

Use CF_Img. It retrieves the width and height for both gif and jpgs. It works by dynamically inserting the width and height parameters into an IMG tag.

Alternatively, download CFX_ImageInfo SE (Special Edition).

A third option is CFX_GIFGD by Jukka Manner

Why do image uploads using cffile not work when using a browser on a Macintosh?

Macintosh browsers (IE for the Mac) may append a space to the filename, which causes the image upload to fail. Adding a TRIM(filename etc) to the FILEFIELD attribute seems to solve the problem.

<cffile
   destination="#request.Folder#"
   action="UPLOAD"
   nameconflict="MAKEUNIQUE"
   FILEFIELD="#Trim(form.Filename)#"
   accept="image/*">
