Passing image file information from form into function, having problems.

[cstegner]

For some reason it wont pass the image variables into the function correctly.
The first if statement in the function keeps stopping it.

Please let me know what I need to do.

Thanks

Do you have the correct entype set in your form?

It should be set to "multipart/form-data".
