Not the best option

First of all the way to rearrange the gallery is totally difficult to handle due to the size of the small preview, a grid kind of preview option would make it much easier to use, and after having put all my images in the order needed, I realized on my website that the quality has been decreased. As a photographer I need the images to appear exactly as I upload them with my own Web-optimisation. really disappointed, WP native gallery works better.
