it's cumbersome that setting width&height for every upload image

[Fatalerr]

when using the admin site for adding or uploading images, you must set the width and height for every image, it's a very cumbersome and unefficient work, Is that any easy way to let it use the original size or auto resize to a default size?

This is just a sample. You can completely ignore the width and height and go with your own implementation where the real image size is uploaded instead.
