For those resource IDs that have been added since Photoshop 3.0. the entry indicates the version in which they were introduced, e.g. (Photoshop 6.0).

Aspose.PSD supports some of these resources. If Resource hasn’t its own Class, you can use UnknownResource from Aspose.PSD API Reference.
PSD Global Image Resources can be used for a big amount of cases. You can get specific Low-Level Data, that you cannot obtain in Adobe Photoshop.
Also, be free to report about Image Resources that you need.Aspose Forum for PSD can help.
