Hey there,

It is the default and correct behavior for it.

If we show it without cropped, the photos will be untidy and inconsistent as shown in the screenshot for an example. https://take.ms/aq2GQ

If you really want to show it without being cropped, you can add the following custom CSS into Backend > EasySocial > Themes > Custom CSS:

body #es .es-comment-attachments a {

    background-size: contain;

}
