Not so much Cake

Not really a Cake question, but using Cake so figured I would ask.

 

Uploading images (the end user, not admin) I have been reading about stenography where the image can contain data / functions embedded in it so in theory the user can edit the url to execute the code embedded.

 

I know have the server / clamshell or what not scan images / files but if you are not serving the actual uploaded image.

If you are only taking a part of the uploaded image using imagecopyresampled or imagecreatefromjpeg / gif / png  cropping re-sizing does that make any difference?

 

Just curious.

 

Thanks all.

Dave
