Hey Sue,
I appreciate your offer here! We unfortunately cannot log into customer sites for any reason; so please do not share any login information here for the sake of security.
If your site will be going live soon, share a link to where we can see an example of your problem and I will work quickly to provide a solution if possible.
In the meantime, you might find some success with WordPress’ various image resizing and cropping tools. You can learn about those here → https://en.support.wordpress.com/images/image-editing/
Thanks!
George
