I am having a problem with this as well.
When I have an image that is placed on the page it rescales fine. I have the image as a circle and it shows really well.
Here it is in display:
Here it is in editor:
However, when I have it in a repeating group and the dynamic image is being retrieved from the database it gets messed up.
Here is the display:
Here is the set up in editor:
I understand that it seems like the main reason is that I uploaded a static image which became a link to :
This link I believe is a cause of the image in the editor to have the width resized, however when I have this image not as part of a repeating group, I am able to resize the image width to be the correct dimension resulting in the appropriate display.
The problem is when it is part of a repeating group, the image is getting resized and I would obviously be unable to manually resize.
How can we get an image that is in a repeating group, that has a dynamic image reference to the database and is using a rounded design have the image displayed with the preset dimensions?
