Angels

We sing quite a lot about angels, especially at this time of year and I`ve been trying to find a picture of an angel for something I`m doing, but somehow despite looking through lots of clip-art images of angels I can`t find anything that seems suitable. Some seem too much like cartoons, others in un-angel like situations, nothing seems right. But then, what do I really expect one to look like – I`ve never seen one!
I know there`s several references to angels in the Bible, but was that the imagery of the time it was written, did it have another meaning, or were/are there real angels? The whole concept of angels is something I find very difficult to picture or imagine. I know we sometimes use expressions like “she`s a little angel” of a little girl that`s exceptionally good, or “you`re an angel” of a friend who`s done us a good turn. But are angels real or are they just imaginary?
