How can I download pictures from RESTful server on a client?

Question

I have a big problem on the download from a RESTful server on an Android client. I have a lot of pictures loaded with the Android client and now I would download these with the same client... I would insert the pictures downloaded inside an image view like a gallery but the problem is: how can I download thie pictures and show in my image view... Json? File transfer? Others? I have read a lot of articles and posts but I haven't got any idea on how to solve my problem... Any suggestion are welcome. Thanks

EDIT: A solution by coding is required because it is an exercise and I would learn the most by using a code
