The following example shows how you can get an image’s information (width, height, alpha, etc) using the <CFIMAGE> tag in ColdFusion,

<cfimage action="info" source="../images/BeBatman.jpg" structName="getImageInfo" />
<cfdump var="#getImageInfo#" />
or by using the imageInfo() as
<cfdump var="#ImageInfo(myImage)#">
Both of which should you image information in a nice cfdump format.
