images on mobile browser

Hello I hope someone can help. I am creating an application that allows people to browse and download images. I know I can't access the photo library from mobile safari, my question is how can I deliver the images to a user? I don't think I can access mobile browsers copy > clipboard with javascript, can I? I am using sencha touch and it seems very difficu开发者_开发问答lt to implement press > hold > copy. Any ideas how you would deliver say 20 images to someone through the phone through mobile browser?

I guess you could email them to the user.

Can't you just display the images and then they can download them to their photo library? On an iphone you just hold down over an image and a sheet will popup asking the user if they want to save an image.
