Hello, I am a 17 years old boy from Hungary, and I have problem with PHP. I hope that you can help. The problem: I ask the width and height of the screen with JavaScript, and when the JavaScript give the values to the PHP they become string, so I can't use the values as a number. I tried to change the type, but it's bad, too. I want that if the screen is bigger, the image is bigger. I enclose a file, which show the problem. I hope that you understand my problem, and sorry about the mistakes. Leskó Dániel
