Hello.
I wrote a script to upload images and then preview a thumbnail.
My upload form is in a seperate file called upload_form.inc
Everything worked until I tried to add support for gif and png in the [I]thumbnail function
Please, what is wrong? is it something to do with the way I nested the if statement?
