This is the final version that has basic uploading, and you can change the upload folder, do incremental upload named, etc on your own.
Within a main folder, an image folder will be created if it is missing, and a jpeg jpg JPG Jpg etc will upload if it has the extension JPG jpg Jpg but not jpeg (you can change that yourself).
The image size matches PHP's built in 2mb limit but with php.ini and the apache server settings in .htaccess depending on your server, shared server, you can change this.
