It just won't open my photo library although it is there in feint print. Next to is says upload 771 of my photos, bit scared to do that!
I have a MacBook Air.
Try this on the MacBook:
Click on the landscape icon.
Click on the Drop image box.
Scroll down the list of options in the grey area to the left until you get to Photos.
Click on Photos and the photos should appear, the most recent first.
It's also possible to 'export' the photos you want to use from Photos to your desktop, but that takes a bit longer - and then means that you have endless photos on your desktop!
Update!
Your post has just arrived as I was trying this on my MacBook! Flicka looks like a young Tuppence!
More photos, please!
