How have you stored your old printed pictures?

I found out that unless old pictures where placed in archival sleeves that none will survive fading,sticking to old album pages etc
I have since replaced all into special archival sleeves and taken
them all out of old albums that held them between sticky pages.
I had also been able to correct faded photos using software suitable for this too.
And as a precaution had taken digital photos of these pictures as a back up file too.
Better check Grandma’s photos or they will not survive.
