I was looking for an easy to use image viewer that when showing the enlarged images from a gallery, that the controls to move to the next/previous picture were fixed and didn't move based on the orientation/size of the photo. This fit the bill perfectly! controls are fixed, the module adjusts the size of the photo to fit in the space, and a filmstrip of thumbnails of all the images is shown at the bottom.
I used the method from the developers website of using the module in an article. works beautifully.
I have also contacted the developer about some other useful features, and he has responded very quickly about them.
