It sounds like you would like to highlight all of the images you’ve added to your project and edit the clip length on all of them at once. I found this information in the iMovie Help resource found here:
Automatically select specific types of content in a movie
- To select all photos: Choose Edit > Select in Movie > Photos.
Then you can adjust the duration of the selected clips all at once:
Thank you for using Apple Support Communities.
- Note: If the adjustments bar isn’t shown, click the Adjust button in the toolbar.
All the best,
