What is the ruling on buying sweets or products that have pictures of living beings on them?

Buying items that have pictures on them is forbidden if the purpose is to acquire the pictures, as it prevents angels from entering the house.

However, if it is difficult to find products free of pictures, then there is no harm in buying them to alleviate hardship, provided that the purpose is not to acquire the pictures, and that they may fall under the category of disrespecting them.
