How to limit image size from image field in a record summary?

How to limit image size from image field in a record summary?

Hello, I am trying to build a Record Summary template to show a summary of a form which includes several types of fields, including a couple images taken from the mobile app. The size of the image in the summaty varies depending on the phone the picture is taken from. Is there a way to standardize or limit the size of the images in the record summary? Ideally, to have it limited by default in the summary, to be able to generate the report directly?
Right now I get huge images in the record summary, also when I export to PDF.
Please let me know the best way to go about this.
Thanks
Constantino
