What is the best way to present a picture taken?

In my app, I take 开发者_运维知识库some pictures and I display them in thumbnails.

I want to zoom them when user touches them.

What's the best way to do this? Thanks

Edit: I've considered a modal view.

I don't save the pictures in the gallery. I display them on the screen, that's all.

If you use the UIImagePickerController you can set it's property allowsEditing to YES to support scaling taken pictures.

Edit: If you already have an Image, please take a look at the UIScrollView
