Still not sure why CF complained, but I am having more luck using this:
<cfhttp
url="http://www4d.wolframalpha.com/Calculate/MSP/MSP79419e1a6ei6h30076g00003170cdffcai81067?MSPStoreType=image/gif&s=55";
resolveurl="No" >
</cfhttp>
<cfset resImg = cfhttp.fileContent.toByteArray() />
<cfimage
action = "write"
destination = "#THISFOLDER#/#imagename#.gif"
source = "#resImg#"
overwrite="true">
Cheers
Stefan
