why not change duplicate a pre-comp and make it independent

[Amonhs298BC]

I have a problem not changing the composition
From composition One to Two But I can't
In the tutorial, he can change the composition, but I cannot
Only I can put it above or below I can't put it on until it changes
I do not want scripts, I just want to shorten the time

No. Wrong link. That is link into your account. 🤔

If you want to change an image in the project - select the image layer in the comp - 

Then hold the ALT key and drag a new image onto the first image layer 🤔

ok this is picture

 

Here is a video tutorial for a person
He can put the composition on the photo, but I just can't. I can put it above or below I cannot put it on

Conclusion: I want to change the composition with the same effect but the picture is different
When I change the image the image is repeated
Not be any different

but here not mine

See bottom picture? You must select the layer in the comp first.

Then hold the ALT key and drag the new layer on top of the selected layer to change it.

Thank you a lot

yes I was able to change it by pressing ALT key 

[Ro Hackett]

Click on the layer in the comp  layer - one

Now hold down ALT on the keyboard and drag comp two down onto one keep holding ALT .... 🤔

As Ro Hackett says you should select the layer first then hold down the Alt/Option key and drag and drop your new comp
