I am trying to create a photo gallery and there are various reasons why I need to create it from scratch. Unfortunately I am very much a beginner and have been using various books and tutorials to try to get this done. Below is the code for my upload file and I have been building it gradually. I have now added the resize function. I had placed this function in a separate PHP file which I called with e require. The function was not found so I embedded it in the file but I get the following errors:
