Can't properly pull images from archive.org .pdf

Setup

• [ubuntu 22.04 ] OS (for example macOS)
• [Google Chrome 119.0.6045.105] Browser version (for example Chrome 90.0.4430.93)
• [Image Downloader v3.4.0] Extension version (for example 3.2.2)

Describe the bug

I'm trying to download images from a [borrowed] pdf book on archive.org (below) and it isn't loading all the images (not a surprise, but not desirable) and when I select the few images that populate and click download it tries to save them as .txt. In the attached screenshot, I clicked the download arrow and it pops up with the filename.txt.

Screenshots

I would really like to be able to scrape the entire book at one go so I can tesseract > piper > ffmpeg > opus audiobook

NB: when I click download, this also f--ks up the book "loan" from archive.org so I have to borrow it again.
