Look up the super global $_FILES['xxx'] on php.net. Your file and it's info are in it. Assuming your form is correct.

Not only that you must store the picture as Binary or Blob data type, and you need more than just the data, such as extension(to deteremine what compression is used), and the size.

I suggest you search on google, there are plent of great articles on the net for upload images and stuff to databases.

Home test beds are useless for development IMO. For that matter, only one server for development can bite ya in the code.

You need to test and develop on a real server and test on more then one server for the best results.
