You can't send raw binary data over http, it has to be Base64 encoded.
This part is required in the Coldfusion page:
<cfset img64 = toBase64(imgBinary) />
<cfoutput>#img64#</cfoutput>
Coldfusion throws an error when using the following:
<cfsetting enablecfoutputonly="yes" showdebugoutput="no">
<cfset imgPath = ExpandPath ("leaves.jpg") />
<cffile action="readBinary" file="#imgPath#" variable="imgBinary">
<cfoutput>#imgBinary#</cfoutput>
<quote>
ByteArray objects cannot be converted to strings
</quote>
If you'd use remoting or a socket, then the Base64 encoding is not required.

Muzak
