I also use Caesium Image Compressor on my ROMs and Themes folder to reduce their size and improve the RG35XX's responsiveness. Source: about 1 year ago

If you want further compression you could check out Caesium Image Compressor which is free (and I'm not affiliated with it incidentally, I just like it). Source: over 1 year ago

Try an image compression tool, this one is free and open source: https://saerasoft.com/caesium/. Source: over 1 year ago

Caesium Image Compressor can do the job and it is easy to use. There is also imagemagick which is basically the swiss-knife for image editing, but based on you having looked for websites first, I assume you don't look for a commandline tool (imagemagick is a commandline tool).

I can recommend Caesium , a utility (Windows, MAC version in Alpha test) to remove all EXIF, metadata etc which will reduce your JPG in size quite a lot without using higher JPG-compression (lower quality). Source: almost 3 years ago

Now it's just a wallpaper changer pointed to a folder of my kids pics This one : Https://johnsad.ventures/software/backgroundswitcher/. Source: about 1 year ago

I used to use https://johnsad.ventures/software/backgroundswitcher/ and it's cool. But latest years I just stick to Snow Leopard. A bit of nostalgia. :). Source: about 1 year ago

I use https://johnsad.ventures/software/backgroundswitcher/ on my desktop PC. Find it a great way to see our travel photos that would otherwise just sit in a folder and not been seen for ages. Just set it to choose a random image from a defined folder every 10 minutes. Source: almost 2 years ago

I use John's background switcher https://johnsad.ventures/software/backgroundswitcher/. It's very customizable for every kind of setup. Source: about 2 years ago

You need a third party wallpaper manager to do that. Many of them have this feature. I use John’s Background Switcher. It can set a different wallpaper on each monitor, randomized from your collection. Source: over 2 years ago
