The two I use are:-
JustPictures! ~ View Flicker, Picassa and all pictures on the Tab.
Works much quicker than the Gallery App and displays much more information including the total photo's in any one folder, when the folder was last added to and EXIF data.
Large Image Viewer ~ View photo's at full resolution.
It is quite surprising just how much detail is lost with the stock Gallery App.
Using Large Image Viewer is very quick and displays photo's in greater detail.
.........I don't always get your questions right.... but you'll certainly know I've tried.
P.S. Many thanks for the Thanks votes. Thanks received are converted into a charitable donation.
