Why won't my pictures transfer from my laptop to my ipad air (PNG and JPEG)

Question

Hi,
I have a 16GB ipad air running iOS 8.1.2 and I have 11 pictures which I need putting onto my ipad so I can use them for my GCSE coursework video which I am using iMovie to do so.
I did the following steps and every time I get a pop up error message saying "the pictures cant be copied because the device has either been disconnected or has stopped responding"
1) open the list of pictures I want putting onto my ipad in windows explorer
2) plug my ipad into the computer using the USB cable included in the box when bought
3) go to: - Internal Storage
                    - DCIM
                         - File Folder
4) select all 11 pictures that I want to transfer and drag and drop on the File Folder
5) error message appears here
These steps work when transferring to my iPod touch 4 running iOS 6.1.2 or my old iPod touch 2 running iOS 2
If anyone knows why this happens or what i can do to transfer the pictures it would be a massive help and would be muchly appreciated
Thanks in advance

You can sync them via your computer's iTunes : connect the iPad to your computer and select it in your computer's iTunes, and then select its Photos tab :
And on that tab select the folder that the photos that you want to copy are in and sync/apply that selection to your iPad.
To remove the photos from the Photos app you will need to do similar to above, but select and sync an empty folder (you can't delete synced photos directly in the Photos app, instead they are deleted by not including them in the next photo sync).
Or you could email them to yourself and use 'open in' in the Mail app to copy them to the Photos app
