I try with this, but no work, can help me?

def Compare(im,im2):
    width, height = im.size #same widht\height for im and im2
    for y in height:
        for x in width:
            pixel1= im.getpixel(x, y)
            pixel2= im2.getpixel(x, y)
            if pixel1 != pixel2:
                pixelvarious=pixelvarious+1
    if pixelvarious > 100:
         return 0

Are they supposed to be the exact same images? because even if its just two images taken one after another of the same thing, from the same place, with no difference because of the level of noise in the image they wont be the same. What you will probable want to do is give them a percentage of error you allow. I think its better if you dont work in RBG but instead in HSV Hue, Saturation, Value (Brightness) http://en.wikipedia.org/wiki/HSV_color_space, there should be an easy transformation from one type to the other. This is helpfull because you can leave the Hue with a very small deviation and give room for change in Brightness and saturation

Let me know if this helpts

mmm, i use the same image (not camera, with the conseguent little difference) i hope that anyone can adjust the code...

Hi dany88a,

What you exactly want to compare? Heigh, width, resolution, size on the disk...?

Please try to explain better what you want.

Also when you post some source code, please use the code tage (#button) instead of putting dots.

as you can see on the source, i want to compare pixel,

Ok here you go.
Check the following code, it works for me

from graphics import Image

def Compare(im,im2):
    width, height = im.size #same widht\height for im and im2
    pixelvarious = 0
    x = 0
    y = 0
    for y in range( height ):
        for x in range( width ):
            pixel1= im.getpixel( (x, y) )
            pixel2= im2.getpixel( (x, y) )
            if pixel1 != pixel2:
                pixelvarious = pixelvarious + 1
            if pixelvarious > 100:
                print "pixelvarious: ", pixelvarious
                return False
    print "pixelvarious: ", pixelvarious
    return True


if __name__ == "__main__":

    image1 = Image.open('C:\\Images\\viewfinder1.png')
    image2 = Image.open('C:\\Images\\viewfinder.png')

    if( Compare(image1, image2)):
        print "Same or almost"
    else:
        print "Images are different"
