Bulk upload of Photos

There are plenty of apps that will send photos from the iPad to the computer, but not the other way round. I have been getting teachers to use Dropbox to transfer selected photos but it is time consuming. I asked the question on the VLN (Virtual Learning Network) 'Does anybody know of a way/app to  transfer lots of photos to iPad but not using iTunes sync?'
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)
 

Photo transfer app, costs $4.19 transfers photos and videos from computer to iPad and the reverse iPad to Computer, a little slower than emailing but still worked quite well. Limit of 200 photos at a time. Buy once and use on all devices (iPods, iPhones)

Photo Sort app, costs $2.59 found that one difficult to use with a lot to setup, some teachers would find this tricky to use.




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.
