I am wondering if OpenGL speeds up the loading image?

Thanks!

OpenGL can speed up the image rendering process, but it can't speed up the image loading, since you'd have to load the file to to memory before dreaming about rendering it, just like any API would have to (Qt included).

Using OpenGL actually slows down reading an image as after reading it has to be transformed into a texture.
