I got several responses and here is my summary below. This is what I tried and what worked well starting with the best
- emailing photos, export from iPhoto or Photos library and compress if images are too big, email to email address on iPad, tap on the share button and tap on 'Save # images', the images go to Camera Roll
Photosync app, costs $2.59 similar to Photo transfer but you need to download the Photosync app companion to your computer to send photos/videos from computer to iPad, photos transferred very quickly. Also transfers to Dropbox, Google Drive, Flickr etc. No limit on number. Buy once and use on all devices (iPods, iPhones)
So the free option of emailing worked the best but I think that I will also recommend using Photo sync and/or Photo transfer as well for the other choices they offer.
