Hi all . i am creating an application that needs to detect the bmp images changes against a perticuler image specification but i do not how. For example if i have bmp1 and bmp2 and the program makes compare if they are identical it does not thing and if they are diffrent it gives me a massage in masssage box that 2 pics are diffrent . and bmp3 comes it compares it against bmp1 and if they are diffrent it prompt me and do this compare ....

All images are of same size . I be happy if some one show me how that can be done.Thanks
