ValueError: invalid literal for int()

[just-smol]

I am having issues since english renta switched from url "us-dre3" to "en-dre-viewer".
Example url https://en-dre-viewer.ebookrenta.com/

I'm not familiar enough with python to know if that's actually the cause, but noted the url was different when trying.
Here is picture of the error message.

After poking and some googling of python syntax and playing around I successfully fixed this error in my own files by changing line 104 to
is_us = True if url.find('us-dre') != -1 or url.find('en-dre') != -1 else False

I was able to fetch my images after that.
