>>7162795I found I had 2 problems with having a large wallpaper collection.
1. Quantity; anything over 2000 papes and you have to start setting the autochange to 1-5 minute intervals changes if you want to start seeing them all. Since we don't hang around the desktop all day we miss about 99% of the wallpaper changes. Set the change interval to something longer and you'll never ever see certain papes come up due to low probability.
Downsize and appreciate the few hundred papes you really enjoy.
2. Quality; yes, you can spend time clean-scaling-up papes which are low res, and granted this is a nice relaxing hobby but it is such a timesink for little gain.
Think for a moment of the sheer infinite nunber of wallpapers that exist and think that you will never ever experience them all, and time spent cleaning one pape could have been used to enjoy 5 other similar ones from the internet, in dimensions that are exactly or higher than your screen resolution.
Sort all your papes by resolution, and delete all of the papes under your screen resolution.
Its painful, I know, I've been there (had nearly 13,000 papes, dont ask, of stuff I had back in 2004 with my old CRT monitor and stuff I liked as a kid which is silly now.) but by getting rid of low-res stuff you spare time which can be invested in finding better papes that fit your tastes and screen res.
Also, you can set papes to "fit" to screen so it uses available pape-res to fit to edges of screen (possibly cutting off top and bottom or the sides) to pape instead lf using stretch or center.
