The ipad and file transfer over bluetooth doesn't work. It likely never WILL work. It's an issue stemming from hardware, not software. Apple's stance on Bluetooth technology has always been one of controversy. It is limited, plain and simple.
You could always upload the pics to Dropbox or email them to yourself or do something similar and download it from there on your ipad.
This is a well documented and highly abhorred issue.
There should be a sticky of what peripherals work and don't work with ipad somewhere around here...I'd use the search function to find it as i can't bring up a link right now.
