I am having trouble resizing images. It works with normal smaller images. I am resizing them to 400 x 600. If someone uploads a 1000 x 1000 photo it works. But some people are uploading images 2300 x 3000 and it doesn't work.
I've used this but it doesnt seem to work.

As mentioned on your other threads, you need to provide more information ;-) Like a code and image sample, an error message, etc..

Here's the code. Its just the resize code.

<cfimage action="resize" height="400" width="600" source="f:\webfolder\sites\#dirName#\#userlogin#\gallery\#filename#.#filedata[x].serverfileext#" 
destination="f:\webfolder\sites\#dirName#\#userlogin#\gallery\#filename#.#filedata[x].serverfileext#" overwrite="true"/>

So what happened when you tried the suggestions on the other thread?

It worked when I installed the patch.
