Questionable Questing epub generation fails to load images

[Kiradien]

When generating an epub from any QQ thread with images in main content fails to load images. URI path to proxy is wrong. It adds full thread path before proxy.php instead of the root (/)

Generated path: https://questionablequesting.com/threads/battletech-the-ghost-who-walks-battletech-isekai.15094/proxy.php?image=https%3A%2F%2Fi.imgur.com%2FE3d9MOW.jpg&hash=7e1afdc066fb54cb44effe1939c8262e
Actual path: https://questionablequesting.com/proxy.php?image=https%3A%2F%2Fi.imgur.com%2FE3d9MOW.jpg&hash=7e1afdc066fb54cb44effe1939c8262e

Additional context
The issue is triggered by a simple uri issue when the source is defined. I have a simple solution that I will push to my own branch, but it might not be ideal.

Simple brute-force PR is up for this, doesn't resolve the source of the problem but eliminates its effects, at least on QQ.
