Editors is a list of editor groups. Each group is defined by its name and files matching wildcard patterns. Order of the groups is important: it goes from top to bottom. Editors' file name is matched upon each group starting from the top of the list.
Name is just user-friendly label. Match is semi-column (;) separated list of wildcard (no regex) file patterns that defines which files will be associated with currently selected group.
Images' relative position in the editor window. Offset is a gap in pixels between image and nearest editors' edge.
If checked, background image will not follow scrolling of the editor.
Various fitting strategies, on how background image is resized for the editor size.

If this option is set, large images will be resized to fit the desktop size. Note it is a desktop size, not IDEA size, therefore, images will be still a bit larger than editor. 100% means images will fit to desktop, 50% means images will fit the one quarter of the screen.
Once again, this is not a simple resizing of the images. This is a definition of the max image size relative to OS display. The small images stay the same, large images gets shrinked.

Slideshow enables image changes in runtime, during user work. Value defines number of seconds between image change.
