26.1; Image files are sometimes not found |

When I start Emacs with "$ emacs -Q", the description of the variable
data-directory reads:
data-directory is a variable defined in ‘C source code’.
Its value is "/opt/local/share/emacs/26.1/etc/"
In addition, I see that there is a file right.xpm with path:
/opt/local/share/emacs/26.1/etc/images/custom/right.xpm
Also, the info manual states in 39.17.2 Image Descriptors:
‘:file FILE’
This says to load the image from file FILE. If FILE is not an
absolute file name, it is expanded in ‘data-directory’.
Hence, I expect the following form to insert right.xpm, which is located
in images/custom/right.xpm relative to data-directory:
(insert-image '(image :type xpm
:file "images/custom/right.xpm"
:ascent center))
However, when I evaluate the form with C-x C-e, I see a blank rectangle
at the end of the form instead of the intended image.
In contrast, changing the form to:
(insert-image '(image :type xpm
:file "custom/right.xpm"
:ascent center))
inserts the intended image. Please note that "images/" had to be dropped
from the path, even though it belongs to the path of the file.
Could you please consider changing the documentation or implementation
to match the observed behaviour?
Thank you and all the best,
Markus
