I was surprised to read that some didn't realise they could up-load their photos in any order, then change the order by moving them around on the listing form. This is called Drag and Drop (D&D).
Is everyone aware that they can also use D&D within THIS PC >> PICTURES to by-pass W10 "Photos" to customise their photo filing system, avoid the Windows default of filing by date and (so far) stop Photos moving your photos into files it creates for you?
Here's how I keep my photos where and in what order I want them without "Photos" interfering.
E.G. To file photos of "Bagley" glass vases "Grantham" and "Wyndham".
Open FILE EXPLORER > THIS PC > PICTURES. Find "New Folder" at top of page > Click. This creates a folder (a DESTINATION) Name it "Bagley".
Using Photos, To up-load photos of a "Grantham" vase. A box will appear to "Change Destination" > Click - this takes you to your folders in THIS PC > Click "Bagley". Up-load photos. They are filed in your Bagley folder. You can re-size, crop, edit and up-load to Ebid listing form etc by opening the folder. To work on individual photos click on it to select and double-click to open.
To make sure they stay where you want them. With the Bagley folder open click NEW FOLDER. Name it "Grantham" > D&D each photo over it and it will move into the folder (and stay there).
To Up-load photos of a "Wyndham" vase repeat as from Change Destination. Use Bagley to get photos to the correct Destination. Repeat the steps to create a "Wyndham" folder, D&D photos to it.
I have 45 folders of Glass manufactures Bagley - Walther. Within each are any number of folders for items or types of item. My Grantham folder currently has three different vases in it. Finding them is much easier than it was when I tried to use Photos. I just open FILE EXPLORER > Bagley > Grantham -- there are only 15 photos to sort through -- all Grantham vases. To sort through the folders within Bagley use the "Bagley" Destination at the top of the folder pages. This can be adapted to file anything in any order you prefer and when folders are empty they are easily deleted.
Hope this is helpful.
