Ability to select excluded images to download

[bumbaras]

1. Filtering selection by width or height - sometimes it is needed to exclude images which have smaller width or height, but we may have one or two images in this group we still want to be selected. It could be done manually but it can't be done now in the case where filter excluded them out. We can see this excluded images on the list but there is no way to select and include them manually other than removing filter and including all the unwanted rest of images. I think addon should exclude images according to filters like it does currently, but still it should allow the user to select manually such excluded images.

2. Sometimes one or more images can't be fetched (server issues, network issues, other errors) and in such cases the red rectangle will appear in the middle of properly fetched images (in the place where the missing image should be). This red rectangle has tooltip under contained full link to image but there is no option to refresh such image. It would allow addon to try to check this failed image once again without the need to check whole page again, but for now it is not possible to do this. Maybe it is this way due to filter which excluded image because addon couldn't get proper size, i don't know. The only way is to repeat operation of detecting everything on such site.

Actually you can press F5 to fetch again. Image Picka uses a cache system so only broken images will be re-download. A better way is to use the Retry on failure option:
