Not downloading all images from IMGUR

[Popupkiller]

My usecase is that I have saved a lot of posts to my favorites, and would like to download them.
I go to my favorites, and to the folder I want to download posts from.
I right click the post and copy link.
I have a third party program that converts the link from
https://imgur.com/user/<any username here>/favorites/folder/<any folder ID here>/<any folder name here>/<post ID>
to
https://imgur.com/gallery/<post ID>

I paste this to Album URL in ImageDownloader, and have log showing.
I click download.
Result on multi picture posts show that all images are downloaded.

Result on single picture posts show that 0 images are downloaded.
Now I have to open all the single image posts after the fact, and download them separately.

if possible, it would be nice to not have to do that.
