Re: image.cfc and custom fields (6.2)

The image formtool uses the Uploadify plugin. It makes one request with XHR
to see if the file already exists (FarCry always returns no, or []), then a
second request through Flash to upload the image. To hook into the response
is a bit tricky, but something like this should do the job:

$j($fc.imageformtool(formprefix,propertyname)).bind("filechange",function(event,results){
    // your code here
});

To get the prefix you can either:

Hook into ft:object r_stPrefix="somevariable" (hint: not actually a struct)

OR

Override the image formtool edit function. Call super to get the default
edit HTML, then tack your custom JS onto the end. To get the prefix:
<cfset var prefix = left(arguments.fieldname,len(arguments.fieldname)-len(
arguments.stMetadata.name)) />
