Hi there Ed, thanks for your question.
If you've deleted your photos, they may be in the Recycle Bin. Press WindowsKey+D to see your Desktop, then double-click the Recycle Bin icon.
If your photos are in there, you can right-click them and click Restore to place them back where they were before they were deleted.
If you've emptied your recycle bin and the photos aren't in there, that means they're deleted permanently. There's no way in Windows to recover them, although a third-party data recovery service may be able to assist in this case.
Hopefully that helps! Please let me know if you need more help. Thanks!
