Images not showing in pdf after update

[npelov]

Describe the Bug

I've installed bookstack long time ago. I don't know exactly the starting version but it was installed on centos 7 with php 7.3. I did have few problems while upgrading but I finally managet to upgrade to BookStack v24.05.4 with php 8.2. I didn't have png support in php which is why images weren't showing correctly. I added png support and now images show on screen but not in pdf exprot. In PDF I see Image not found or type unknown. The problem is only with old images - uploaded before the update. When I create a new page and upload new images the images show just fine in pdf.

Steps to Reproduce

I'm not sure

Expected Behaviour

Images should show in pdf
