Oh, from an Iphone? Are pics actually in the pictures folder? What happens when you "click a pic" ?
Are the pics file type associated with the metro photos app?
When in the app, what do you see when you right click? Can you import your pics?
I download a picture from the Iphone. I showed up on the start picture app. I deleted all the pictures in the file except the one I just loaded from the phone. I cut and pasted the picture to the desktop. I moved the picture back to the picture library and now it doesn't display.
Try to find some pics. Do you have, let's say 20 pics. Copy them from somewhere to the pictures library folder. How many pictures do you have in your pictures library folder?
Your Iphone has a way to transfer pics from storage to a folder on your computer. Copy them to the pictures library folder.
What happens when you select to open a pic with "Photos" ?
I copied a new picture to my desktop. I did what you recommended to do on your last post and opened the picture with Photos. I then copied that picture along with 2 others that were on my desktop and placed them into the empty default picture library folder. The 2 older pictures showed up but the new picture didn't when I opened the app.
I just noticed something. I copied 5 pictures from an old hard drive and pasted them into my picture library They were grayed out compared to the other pictures and didn't show up when I started the app.
