Hi,

To make a display for GIF frame with a read function the code looks like below

allframedata = imread('YourFile.GIF', 'frames', 'all');

alldimensions = size(allframedata);

number_of_frames = alldimensions(end);

you can refer the below links

And for steganography of gif you can use LSB algorithm

For implementing LSB algorithm you can follow the below link
