Uploading images to a theme
To upload a new image to your theme go through to the page editor and click to enable advanced mode.
Click the 'upload' button.
A new window will then appear for you to choose the image file and click 'upload'.
Once the file is uploaded it will be displayed in the images folder.
Warning!
Your file name should not contain any spaces, instead you should substitute spaces for the - or _ character.

The URL of the image in your site's pages is rendered using the {{ asset_url('') }} tag.
You'll need to still use the <img> tag and include the image file name within the '', e.g.
Referencing the image in CSS
If you are referencing the image within CSS, the correct path to use is
../images/filename.png

background: url(../images/filename.png)
