Pearce, to copy a picture:
Long press on the pic/image you want
Box will come up, select save image
Go to downloads, should be in short menu or press settings, storage, downloads and select file
Gallery will be an option,select that and pic will be in your Gallery.
To transfer a picture, there are several apps, just put WiFi transfer in the app search function and it will bring up several apps. Let me know if you need help with whatever app you select, but most are self-explanatory.
