Can I somehow let the user select multiple images from device?

Is there any way to let the user select multiple images from the device media gallery?

The CameraRoll only selects one image. And the FileRefernceList doesn't show thumbnails (so you have no idea what you are selecting).

Is there a way, or maybe some sort of workaround, for this? Is there a way to maybe "read" the users gallery on the SD-card and output your own gallery that the user can select from?

I'm developing towards both Android and iOS so cross-plattform is a must.

Thank you guys
