Perfect, thank you so much! All seems to be ok.
I also have a couple of other queries…
When I look at the form I’ve created with a phone or tablet, even though the images are stacked, because I’ve specified a height in the image options, they all appear at that height.
Ideally, I need them all to show in the correct ratio which is 3/2.
Is there anything I can do so that they resize all automatically in the correct ratio irrespective of what device is being used to view them?
