Convert an image from CFHTTP filecontent to binary data with Coldfusion

I'm trying to convert an image (jpg) loaded via cfhttp to binary data. I can't use cffile action="readBinary" as it is not a local file.

Here's how I handle this, and I use this to grab and process hundreds of images a day with ColdFusion 8.

<cfhttp
    timeout="45"
    throwonerror="false"
    url="http://domain/image.jpg"
    method="get"
    useragent="Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.12) Gecko/20080201 Firefox/2.0.0.12"
    getasbinary="yes"
    result="local.objGet"
>

<cfset local.objImage = ImageNew(local.objGet.FileContent)>

Once you have the image object you can then do whatever you want with it. Save it to disk, resize, you name it :). I've obviously left out all of my error checking (200 status codes, is it an image, etc), but this should get you started.
