If you have output formatting requirements different than the default output of ->display(), either check the field options to output as a gallery, or iterate the data returned by ->field(), which will usually be an array of attachment IDs.
When working with fields which are images, there is also do notation for quick references to image thumbnail sizes, but be aware that when working with a field which allows multiple files, you will likely receive an array of values rather than a single value:
See: https://docs.pods.io/code/pods/field/field-notation-options/ (For example ->display( 'project_image._img.sizename' ); …which will behave differently for a single-image field versus a multiple-image field, and again will behave differently for ->field() versus ->display()
Aside, noticing in your screenshot that there are more than 700 fields on a single post type…
While that’s not causing the reported issue, and may be working fine for your use case at the moment, it important to note that fields on one post type will all appear in one administrative page load…
Therefore, if a human is expected to load your data architecture with a browser, at some point the browser will crash, depending on the user’s resources (Consumer Laptop? Phone?)…
Unless the architecture is meant for a machine, or the WP Admin edit screens are not being used, a user interface design which specifies “the user should see seven hundred choices on this screen” usually indicates new possibilities may require consideration.
Thanks, if you have found a separate reproducible bug separate from use of the API, please file details on the GitHub issues. If there is a sepecific item you need help with understanding, open a new ticket in the forum here.
But overall, please differentiate between a bug in the plugin versus a bug in custom code you are writing with various expectations in contrast to reality documented in the open code or published examples. It may also be helpful to use error_log, print_r, or var_dump to inspect the contents of variables being worked with in PHP.
