Hello fellow Daniz, i working on a website and am trying to upload images but i keep getting an error stating that i have undefined functions in my code, could someone point me in the right direction here.
My code is below.

Could you post the error. Does it indicate what line the problem is occurring? It'd save time reading through all the code.

Its fine, I worked it out.
