Reply To: How do I change the content percentage on multiple images at once?

1. Select one image, not the frame
2. Set the size to 25% > this value is stored in the clipboard
3. Select all images, by selecting with the black arrow and choose then Select content from the control panel
4. Object > Transform again > Transform Sequence Again Individually

Note that your grid will be destroyed, if you choose frame to content in the next step.
