What is the purpose of reinstalling all the default images (everyone probably changes them to their own) during upgrades?

I reckon it would be possible to upgrade files, and maybe even add new images, without overwriting community images your customers have designed to fit their community.

Is there a way to upgrade only certain files, and not the whole thing?

Also, it is really annoying with the css files on one line. What is the purpose of this? I really cannot imagine anyone works with css on one line, and it feels like it is done this way only to complicate things for the customer. Yes, I know about override files and folders, but it's still a major job reading and understanding the original document.

Hi, Trude.

To what images are you referring to?
Images like "guest-bg.jpg"?

The best solution is to override them via css e.g

#community-wrap .cGuest .hero-area {
    -moz-box-sizing: border-box;
    background: url("../images/guest-bg.jpg") no-repeat scroll 0 0 / cover rgba(0, 0, 0, 0);
    border-radius: 6px 6px 0 0;
    color: #FEFEFE;
    text-shadow: 0 1px 3px rgba(0, 0, 0, 0.25);
}
