Hi, its been a few months, and I'm still waiting to hear of any definitive solution or feedback on two bugs inherent to the photo plugin.
The first is the inability to edit/change album covers as well as set a specific photo to be an album cover. This occurs only when using amazon s3 services.
The second is a timeout error that occurs when uploading larger size photos in bulk (e.g. uploading 10 photos, 5mb each)
