Similar to the image saved size settings where it is possible to set the maximum resolution in which the image is stored for a limited memory capacity device.. it should be also possible to only set the dimensions in which the images are previewed in the library view forms..

In other words i want to store full resolution images but only preview the as thumbnails.. once tapped i get to display them in full screen and high resolution..

Multiple thumbs can be previewed on a screen vertically or horizontally.. carousel

Full resolution images can also be shuffled or scrolled throw..
