Okay, so it's still not working. This is what I got in my css (along with other things which are working, so I know it's seeing the CSS)

html{
	background: url("plugins/node-theme-nodetendo/images/cover-bg.jpg") no-repeat center center;
	background-size: cover;
	background-color: #000000;
}

And this is whats in my plugin.json now (which I copied from vanilla, and added @julian's lines to:

{
    "id": "nodebb-theme-vanilla",
    "library": "./lib/theme.js",
    "hooks": [
		{
			"hook": "filter:widgets.getAreas", "method": "defineWidgetAreas", "callbacked": true
		}
	],
	"staticDirs": {
		"images": "static/images"
	}
}

But I'm still getting a 404 on the image, and it's not loading up.

PS: How are you guys doing the blue thing? I tried a [quote] tag and a [code] tag, and none of those worked.

@a_5mith I silently fixed that problem, but I'm currently using FTP to upload my themes, and won't be updating the github one until I get more done.

@julian I'm going to try that now. Thanks for letting me know about that.

Ohh, thanks for the tips.
But do you know of a way I could keep my images on the same server as the nodeJS instead of having to host them somewhere else? Cause I kinda want my images to come with the theme, you know?

Yeah, it showed up. Also it's pretty could you tell me how to do that some day?

Thank you very much for your quick reply, but it didn't seem to work. My image is in "/root/nodebb/node_modules/nodebb-theme-nodetendo/images/" on my server, and I tried using both:
http://198.199.111.179:4567/node_modules/nodebb-theme-nodetendo/images/cover-bg.jpg and http://198.199.111.179:4567/images/cover-bg.jpg in the background image variable, but it didn't work for any of them.

So I'm trying to get some CSS background images to show up, and they aren't. So far I've tried:

background: url("node_modules/nodebb-theme-nodetendo/images/cover-bg.jpg") no-repeat center center;

and

background: url("../images/cover-bg.jpg") no-repeat center center;

and even just: background: url("images/cover-bg.jpg") no-repeat center center;

But none of them are finding the image.

Can someone tell me the proper path to get theme specific images loaded?

Yup, title worked. Thank you!

So I'm trying to display the "Site Title" from the General Settings, and I can't figure this out. I tried {siteTitle} and some other ones but it's showing up exactly as I type it.
How do I display the "Site Title" in a template?

Thank you all for your help. I got it working! It was actually a error in the tutorial that I managed to figure out.
Here's a link to how I did it: https://github.com/CyanPrime/nodebb-theme-nodetendo/commit/70b4938097f083df01ec724b28c4041a0f6c7d3c

And here is the erroring tutorial: http://burnaftercompiling.com/nodebb/nodebb-hands-on-theming-guide-part-1/

Once again, thank you all.

Thank you very much, @a_5mith
My forum is working again!
However, my custom theme still breaks NodeBB. Can anyone tell me why? I'd love to become a theme dev, but I can't really do that if my themes crash the BB

Alright, I figured out the error:
[themes] Could not find base template files at: /root/nodebb/node_modules/nodebb-theme-vanilla/templates

The thing is aqll the templates are there, and even when I copied the templete folder into my nodetendo theme it still said the same thing on ./nodebb log.

So after getting and installing my theme here I'm trying to start
https://github.com/CyanPrime/nodebb-theme-nodetendo
I can't run NodeBB, or get back in to switch my theme back.
I also can't figure out what went wrong.

Can I get a bit of help?
