I take into consideration the average of the amount of paid for each image (going on estimates as I can't remember every image) and then remove a bit.
I've seen people do it a few different ways, but I wonder what you do in terms of calculating their total value.
I know that when it comes to cash value you that you'll take into consideration everything you paid for.
But do you log it on a google docs sheet, is there a tab on your characters profile?
I hope I put this in the right area, but it didn't seem to casually fit anywhere else tbh. 👀
