Hi Gerald,
When all else fails, the manual approach is your best option to transfer the files, the built in Photos App can be a bit unreliable, and you will have more control over the files are transferred . . .
Open Windows Fie Explorer (folder icon on your Taskbar)
On the left click 'This PC'
On the right double click your Memory Stick
Then simple select the files you want to transfer and drag them into the Pictures folder in the left pane of File Explorer
That's it!
