But that is not the way it works.
Sending a file to Recycle Bin does not remove it from your hard drive, all it does is re-write the file allocation table to show the file in RB rather than the folder you had moved it from, but it is still taking up the same amount of hard drive space. It is only when you empty RB that you free up drive space.
A better alternative perhaps would be to create a folder called, say, 'Unused images' and create identically named folders in this for images you may or may not want in the future. As an example, you have been shooting primroses, so you have a folder in your image file called 'Primroses' with the photos in it. You decide that Primrose_3 is the one you want to use so you move the unwanted _1 and _2 into \Unused images\Primroses\
You could use cloud storage but beyond a few GB it starts getting expensive. I have about 500GB of photos on my system, with them and about another 400GB of duplicates on external storage. External HDDs are relatively cheap today.
