Repeat grid feature counterintuitive.
Most of the time I find myself trying to replace only one picture but all pictures on the grid get replaced. I know it's a use case but please give be a modifier while replacing the picture because I need to build my own order one by one and this is not possible. In order to do this I need to ungroup the grid and then all the magic is gone.
And it's completely inconsistent: I can replace a single text on a box by typing but can't do it with another element of the same group (picture)

Yes, if all images in the grid use the same image file, then dragging a new image file will update them all.
But, if you use multiple images, then you can replace a single one (kind of). Try this:
1. Drag 3 images to your grid element. Display pattern shows a different image in each of the first 3 cells, then repeats that pattern, pattern length is 3: img1, img2, img3, img1, img2, img3, ...
2. Drag a 4th image to 3rd cell (inside original pattern). 3rd image in pattern is updated in all cells, pattern length is still 3: img1, img2, img4, img1, img2, img4, ...
3. Drag a 5th image to the 6th cell (outside of existing pattern). Pattern is updated so that the 5th image is in every 6th cell, pattern length is now 6: img1, img2, img4, img1, img2, img5, img1, img2, img4, img1, img2, img5, ...
As you drag in new images, the pattern is updated in this pattern (that I hopefully explained in enough detail).
When I said "you can replace a single one (kind of)", what I meant was that if the number of cells in your grid has fewer cells than where image appears in pattern the second time, then it only a single appearance is shown.
Does that help?
