File --> Replace Footage. As simple as that.
Save your project as a template then do as Mylenium suggested, replace the footage.
Inside The Timeline panel, I can select the Image, and Alt Click on my Project panel Image and Drag and Drop It into the image and It dose replace the older Image.
Is there a way you can Replace for example 50 images at the same time ?
Thank you very much
Only if they have the same name. You could set up a naming convention and a folder structure then use bridge to rename your images then just drop the renamed images in your project folder and the. Open AE. As long as you can keep the files straight this is the easiest way that does not involve advanced scripting.
Yes Sir, I did exactly what you told me. I Created a test folder with 10 images named them 1-10, and created a Slideshow, closed After Effects and opened new Images Named them 1-10, and later I did copy 10 Images named 1-10 into that folder and It Is Working.
Thank you very much for your help
