Hello & welcome to the forum!
Now there are many possibilities, and not sure if you want to transfer the entire folder or just the images contained in the folder? Also, will this be a need in the future, i.e. do you want to transfer a lot of pics often which will impact on your choice(s)?
BUT, I will simply list some of the ways that I've transferred photos 'back & forth' between my computer (use to be a PC now a MBPro) and my iPad:
1. iTunes - you can always sync between your computer and the iPad - I find this option painful but works!
2. Apps are available - I've used
PhotoSync for a number of years - need apps on your computer & on your iDevice - both on my old PC & on my new MBPro.
3. AirStash (see pic below) - Maxell offering which sets up its own network and allows transfer between and iPad & a SD card (which can be plugged into a computer) - works both ways.
Now that's just for starters - there are obviously other choices but maybe this will get you started - good luck! Dave
