How do I make bluetooth transferred photos show up in gallery?

Hello, i am using a Galaxy S3 and i'm having some trouble. when i receive pictures via bluetooth, they don't appear in the bluetooth folder in gallery. when i check the bluetooth folder from my files, the pictures are there. the same goes when i use some picture editing apps. i saved them already but they only appear at my files, not at the gallery. what should i do so that they appear in gallery as well? thanks!

And please don't just tell me to use a different application
