Simply navigate your PS4's browser to the URL of the wallpaper image you'd like to use, fullscreen it and take a screenshot with the share button. Then head to your Theme settings, choose 'Custom' & you'll find your screenshot in the 'Other' folder. Easy!
If you'd like to use the same STR wallpaper as I tweeted above, just point your PS4 browser to http://bit.ly/2m2rGn3. Alternatively, you can find lots of other STR wallpapers on our main site here as well, should you fancy!
(You can ofc use this as a desktop wallpaper too)
Have fun
