exists(image) is true even when the image is not there yet

Good morning.

I am developing a game bot with infinite loop with many if's conditions, it's almost done, the main problem is one of the if exists(image) is getting true when the image is not there.

example:

while (ch.hasWindow() & running):
....
            if exists(image1):
                do something
                break

            if exists(image2):
                do another thing
                break:

            if exists(image3):
            ....
                img = find(image3)
                click(img)
            ....
...

The if exists(image3): is the last if inside while loop, but it's getting true even when the image is not there yet.
