It turns out that to get the relative path conversion w have to remove any
quotation marks around the path before running os.relpath(). So the script
becomes:
"""Insert RsT code at cursor to display an image.
The path to the image file will come from a file dialog.
This action is undoable.
"""
PATH = g.app.gui.runOpenFileDialog(c,
title="Import File",
filetypes=[("All files", "*"),],
defaultextension=".*",
multiple=False)
if PATH:
from os.path import relpath
PATH = PATH.replace('"', '').replace("'", '')
PATH = relpath(PATH)
PATH = PATH.replace('\\', '/')
IMAGE_TEMPLATE = f'''
.. figure:: {PATH}
:scale: 50%
'''
w = c.frame.body.wrapper
p = c.p
s = p.b
u = c.undoer
start, _ = w.getSelectionRange()
undoType = 'insert-rst-image-code'
undoData = u.beforeChangeNodeContents(p)
head, tail = s[:start], s[start:]
p.b = head + IMAGE_TEMPLATE + tail
c.setChanged()
p.setDirty()
u.afterChangeNodeContents(p, undoType, undoData)
c.redraw()
