cfimage won't let go of my file so I can't delete it.

I am designing a client image uploader that will also process the image—resize, sharpen, etc. Right now I am just working out the uploading bugs, namely if the client wants to replace the image.

It appears that, once uploaded, ColdFusion is keeping the file in memory, so I can't delete or overwrite it until some undefined time afterwards (presumably once the file is kicked out of memory). I am not sure how to get ColdFusion to release the file so that it can be deleted.

You can see I have a try/catch statement; this is where the code is erroring out. Sometimes, if I click the refresh link inside the catch statement it will finish through the rest of the code, but most of the time, it just errors out.

If I upload an image for one event, move to a different event and upload an image for that event, and come back to the first one, most of the time I can replace it, but I really don't think it's unreasonable to upload a file and then immediately replace it (e.g. if the user accidentally uploaded the wrong image the first time).
