Pinta can not open file - permission denied

My ubuntu 18.04 is installed in the SSD.I installed pinta from ubuntu software but can not open files from my hard disk, says permission denied. But can open files from SSD where ubuntu is installed(Document, Download... folders). How do i give permission to all the drives. Facing same problem with some other apps too.

Files from Computer is accessible to pinta.

Here is the findmnt | grep /media command output

When I click Details I get the following information:
