Photo Station uses thumbnails that are generated from Media Library. However, Media Library does not create thumbnails if:
1. The NAS is out of memory (Other applications may be using the resources)
2. The NAS is out of storage
3. The photo resolution is too high (Refer to the following table)
|Resolution (pixel)||Create a thumbnail? (Yes or No)|
|51 million||Yes, if the NAS has at least 1GB of available memory|
|240 million||Yes, if the NAS has at least 2GB of available memory|
If none of the above situations apply, please restart Media Library.
