I am unaware of any FilePicker control in Xamarin.Forms. As such you need to create your own FilePicker control in Xamarin Forms.

This is fairly easy, you can just have a list view that shows the folders and when you click on it, it goes into the folders and shows a list of files.

However this will require Dependency Injection to get the list of files and folders.

Xamarin.Android has an example here, you can ignore the UI stuff and just look at the code in retrieving the data

And for Xamarin.iOS

Can I Convert from Xamarin.Forms.Image to System.Drawing.Image then use Image.Save(image) – Mohamad Mahmoud Darwish May 14 '16 at 10:57

To send to a server you need to build an API on the server and send the image through, generally as a byte array. Something like: http://stackoverflow.com/questions/33367834/send-image-to-webapi-service – Adam May 15 '16 at 01:47
