After doing a cffile action=”upload”, I’d like to check the width (assuming it’s a image). I’m currently using CF8.

    The example provided by Adobe should get you going:

<cfimage source="../cfdocs/images/artgallery/jeff05.jpg" name="myImage">
<!--- Retrieve the information associated with the image. --->
<cfset info=ImageInfo(myImage)>
<cfdump var="#info#"></cfdump>
<p>height = <cfoutput>#info.height#</cfoutput>
<p>width = <cfoutput>#info.width#</cfoutput>
<p>source = <cfoutput>#info.source#"</cfoutput>
