WHY IT NEEDS A POLICY

Why photoshop_open_image needs a policy

Opening an image file creates a new document in Photoshop, which is a Write-level action (creating new state). It does not delete or overwrite anything, does not execute arbitrary code, and has no financial implications. The blast radius is low since it only opens a file for editing without modifying the source file.
