RE: It’s strange that this connections plugin does not use the WordPress image library.
Actually Connections utilizes the WP core image processing functions. I do believe the error you are seeing is from the WP core. I’d have to dig into to the code to confirm that though.
Where WP core and Connections differs is WP will serve full sized images instead of smaller cropped images if it is unable to make them. Image uploading a couple multipl meg pictures to post, instead of sizing them down, WP will simply serve the full image which is rather inefficient.
Because Connection can show quite a few entries on a single page, it will never serve the full sized image, only the smaller cropped versions.
Let’s try this…
Navigate to the Connections : Tools admin page and click the System Info tab. Scroll to the bottom and generate a secret remote viewing link. Copy that link and reply back to with as a private reply so I can take a look.
Another item to try, upload a JPEG version instead. Do you still get the error message?
And, out of curiosity, navigate to the Media Library and click one of your larger images. Does the “Edit Image” button appear? If it does, click it. Can you rotate/flip/crop the image?
