If Webshots says you have a "Permissions Problem" or if Webshots says "updating your photo library" every time you open it then this problem affects you.
Some users who have upgraded earlier versions of Windows to Windows 10 report that the "Documents" directory is no longer writable. (Do a google search of "windows 10 documents read only").
To Fix this, please follow these instructions:
a) Right-click on "Documents"
b) Un-check the "Read-only" checkbox
c) Click "Apply"
d) Restart Webshots
