Many images are shown as thumbnails in the program interface. Many? Yes, not every image is shown there. I’m not sure if this is a bug or a limitation. The screenshots on the project page paint a different picture. It is not a huge problem but makes the software look inconsistent. All images, regardless if a thumbnail is shown or not, are downloaded to the local hard drive. They can be opened from within the program interface, or from the local directory they have been downloaded to.
Another interesting option is to create a new download tab to download pictures and images from a different 4chan thread as well.
A user could theoretically create download tasks for an unlimited amount of 4chan urls. On top of that, all could be monitored by the application for new images.
What’s missing? The developer needs to work on the thumbnail display. Either display all images as thumbnails or none, the current solution is not satisfactory. An option to add multiple threads at once, or a whole board, would be welcome as well to automate the downloading further.
