DejayM. The previous IOS Yosemite would not allow drag and drop from Photos. The new MacSiera you supposedly can. But I was not able to do it.
The easiest way is to drag it from Photo (Once you press DONE (Saving it)) to the desktop and immediately to Ispot. Otherwise I am doing DejayM is suggesting: Choose Images and Select. I have to do it that way because the photo is locked in Photoshop Lightroom after any changes. Which is good!
