If I edit a photo in Photoshop I can only save it iCloud Drive. How do I get these photos into my photo library?

I edit my photos in Photoshop on my iMac and need to open them in drawing/painting apps on my iPad to work on them further. I can only upload edited Photoshop photos into the iCloud Drive from my iMac. Can't figure out a way to save them in the photo library or to transfer them there from iCloud drive. This is a problem because my iPad drawing apps only access the iCloud photo library, not iCloud Drive, even though I have the iCloud Drive option button turned on in my iPad settings. Please tell mehow to access photos from iCloud Drive from my iPad drawing applications. Thanks.
