I don't want to waste yours and my time doing more if they aren't needed.

I don't really know. I'm guessing it might help reduce the sizes of the artwork-packages somewhat, so the packaging team might find this useful, as well as Adrian who uploads the monthly updated isos.

But I'll leave them to respond.

Thanks for doing it anyway!

Thanks for your replies, your comments are greatly appreciated. My delayed response is due to a knackered modem.

I am going to continue to optimize images as I'm a bit OCD about those which have a huge file size. If the images are of use then I'll be happy

I've had another bash at the login / grub images. I have reduced the image sizes by 60%, greyscaled and optimized them. They look better, and the total size of the files is down to 212KB.

The files are at https://postimg.cc/gallery/16vqqgtso/

I ran guetzli on your reduced images, and it reduced them further by 10-20%. What would be really nice it we could shrink then all with Linux tools like imagemagick and guetzli on the command line, so we could just run a script on the folder full of images.

After running guetzli on them, I couldn't see any change at all when switching the original and reduced version in nomacs.

Who's in charge of the github for the artwork packages? That's where the new files need to go.

Batch optimization is not recommended. While some images optimize without problems others will suffer from artifacts, and these artifacts can be real bad. A friend of mine batch file optimized images I had previously optimized for his website in the hope of saving a few KB. His images were trashed - fortunately I kept copies and his website was easily returned to its full glory.

Quality optimization requires the images to be dealt with on an individual basis, and this is Smartsaver Pro's specialist subject.

I have redone the grub / login images, they have been slightly softened. This has reduced the total size of the files to 160KB.

Would it be of benefit if I optimized the wallpapers at https://mxlinux.org/wallpaper17?

It would save bandwidth, but if this isn't an issue then I won't bother.

Please do that before continuing.
