Hi, I need to save an image to my gallery, but not from a canvas. What's the method to accomplish this?
Your image will need to be in Shared Storage to appear in the gallery. You may need to refresh the gallery with an extension to be able to see it there.
It was beyond my understanding. Please provide a brief explanation.
Use the GalkeryRefresh method from the tools extension
The image must be available in shared storage

I get it, but what kinds of blocks can I use? I prefer it to be in the download folder.
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.
