Is it obligatory to efface pictures on book covers to prevent angels from being veiled from entering the house, and do pictures on recycling bins have the same ruling?

The widespread presence of images in books, magazines, and on food packaging has become a common affliction. It is not incumbent upon a Muslim to track them down for erasure due to the difficulty involved, and this falls under the category of necessity for which forgiveness is hoped. As for the images that prevent angels from entering the house, they are images of animate beings that are not treated with disrespect. Permissible images, such as pictures of natural landscapes and images treated with disrespect, do not prevent angels from entering. Images in recycling bins are considered treated with disrespect and do not prevent angels from entering the house.
