What is the "tasweer" (image-making) mentioned in the noble prophetic traditions, and does photographic and video imaging fall under the concept of "tasweer"? Is it permissible to hang pictures of cartoon characters in bedrooms?

Cartoon images for children are permissible provided they are free from anything unlawful. It is permissible to hang those that are permissible in rooms, as long as they do not lead to temptation or glorification. However, it is preferable not to hang them.
