For my X100T, which I understand has the same wifi capabilities as the XT1, I use Fuji Camera Remote as it also gives me the ability to control the camera remotely from my phone and to geotag my images as well. Both the Receiver and the Browse Camera sections of this app allow the sending of up to 30 images at a time.
High resolution jpgs (486 x 3264 pixels) are accommodated, but any raw counterparts are ignored. I believe this free app to be more recent than alternative free apps available on the Play Store(Fuji Camera Application and Fuji Camera Receiver) which is another reason for choosing it.
My only beef is that images transferred from the camera are renamed to some horribly long date/time based format. DOES ANYONE KNOW HOW TO AVOID/TURN OFF THIS ANNOYING FEATURE?
