I am trying to show images in the circle option but the image keeps being shown as an oblong.
I have made the images a square shape i.e. 635 x 635 thinking that it would convert to a circle quite simply but no that is not the case. Can anyone please help me?
I am uploading a screenshot of what I currently see

This is what I am attempting to create - it was done by a friend who is unable to be contacted at the moment for personal reasons.

I know it can be done I just don’t know how.
Thanks Heather & Louise
