Here is an example, how you can upload a file.

Write a form like this (note that enctype="multipart/form-data" parameter is required):

<form action="upload_handler.php" method="post" enctype="multipart/form-data">
     <input type="file" name="img">
</form>

And the upload_handler.php would be:

That's it! Reed more in PHP docs: http://php.net/manual/en/features.file-upload.php

If you need to resize the image, you can use GD library for PHP: http://icant.co.uk/articles/phpthumbnails/
