Saving Straight to Mac Photos

There was a function I used to do that seems lost now. I get an image from the Mac Photos app, open in Topaz Gigpixel, make changes, and SAVE TO ORIGINAL FOLDER would make the new image show up in Mac Photos right next to the old image.

That does not seem to happen anymore. So, I save the image to another folder and drag it to the Photo app, and somehow it appears next to the pre-edited photo.

Any tips for easier saving back to Apple Photos?

This feature was temporarily removed because there were plug-in issues.
