In the Name of Allah, the All-Merciful, the Mercy-Giving

 

 All praise is due to Allah. Peace and blessings be upon His Messenger Muhammad.

 

According to a number of hadiths, it is prohibited to make or keep an image for a living creatures; particularly if it has a shadow. If the image has no shadow but is erected or placed in a way that indicates respect or veneration, still this is totally prohibited. However, if such images are used in disrespectful way, as in carpets and bed sheets for example, there is no harm in keeping them.

 

Accordingly, if these image are small and placed in hidden places, that would be a sort of disrespect to such images, which renders it permissible to keep them. If, however, these images are big and noticeable, then if you can make any change (by removing or adding) in the appearance of such images that they look no more like full images for birds, that will be fine; otherwise, you should not keep them.

 

Almighty Allah knows best.
