I moved the project to gitlab:
https://anonym.to/?https://gitlab.com/UISQN/imgding
and released a new version, which fixes two things:
- #3 Firefox/Chromium: After opening a new browser window the links are collected from the old browser window in the background. Now the tab of the active window is used
- #1 Download fail detection improved. Firefox (not Chrome) sometimes downloaded missing images from imagebam as small html files. Now all downloads smaller than 1KB are considered as failed.
The new version is available in the mozilla addon store, chrome web store is following.
