Change the color of "drag" and "delete" icons to make them more visible against white bkg.

SOLUTION 3
Change the size of "drag" and "delete" icons to make them more visible against white bkg.

Additional context
This was raised strongly by users at 2021-11-17 MMA focus group meeting (https://www.dropbox.com/s/mlym1xn77t5q74n/2021-11-17_MMA%20GUI%20usability%20feedback_zoom_0.mp4?dl=0)

This was partially addressed when we increased the size of all icons on top of each image when we implemented the Cut and Paste solution.
The issue is ameliorated but not solved.
