Suspended in v5.0.0 through v5.5.4 due to conflicts with the new text engine, from v5.6.0, pictures may once again be inserted into the background of a map view as picture adornments. Note this restoration of the original method of making map picture adornments is temporary because it is likely to be replaced in the future by an updated method (to achieve the same aim).
Like text adornments, picture adornments don't show up in any other views, and don't affect the hierarchy or the links of any notes. Locked picture adornments are ignored from drag-selections of notes.
For an image to be available to insert as a picture adornment, the file's contents must be copied to the clipboard. Thus first open the file in Preview (or an image editor), 'select all', 'copy'; the content is now on the clipboard ready for pasting and image may be closed. Picture adornments can only be inserted via the Map view pop-up menu (a Cmd+V paste will not work).
Drag/drop from Finder windows was not originally supported, but from v5.9.0, Cmd+dragging an image from Finder into a Map view will create a picture adornment.
[Following may not hold true post v5.6.0] Images are inserted and displayed at 'actual size' (i.e. for current desktop resolution - normally 72 dpi). Resizing the picture's 'frame' won't zoom the image size but it will crop it if smaller than the image. The image does scale if the whole map is zoomed in or out.
The image format must be a bitmap image, not vector-based (i.e. CAD or EPS). The image files may have the extensions (formats) .gif, .jpg, .jpeg, or .png.
Just as normal adornments aren't exported in HTML Export, neither are picture adornments.
From v5.9.0, picture adornments respect $Opacity and may have non rectangular shapes, just like normal adornments.
