I think the issue you are running into is that you must do at least
three steps, load, some manipulation, and write. If you call each one of
those methods using separate <cfinvoke> calls then it won't work because
you are using three different instances of the same CFC. Personally, I
would do it all in <cfscript> like as follows.
<cfscript>
imageUtils = CreateObject("component", "yourCFChere");
imageUtils.load("filepath");
imageUtils.thumbnail(250);
imageUtils.writeResult("resultpath");
</cfscript>
