[1.1.1]Images in RobotFramework library .sikuli folder not found

not a bug, but imagepath settings are not appropriate for this kind of RobotFramework usage together with SikuliX

--- the relevant error message from the main script:
[error] Image: could not be loaded: file:/D:/script/robot_CalcDemoEx1.sikuli/1467617880602.png

--- this is the library setup in RFW script:
*** Settings **
Library D:/script/UserLibForSikuliXEx1.sikuli/UserLibForSikuliXEx1.py

UserLibForSikuliXEx1.sikuli contains the missing image, but is not on the image path!

reason:
only .sikuli scripts, imported by another .sikuli script are automatically put on the image path, so that images can be loaded.

The library UserLibForSikuliXEx1.py is internally imported by RobotFramework, which does not know anything about SikuliX's image path.

solution:
either put all images in one place and take care in main, that this is on the image path or in this case, in main before running robot add an
import UserLibForSikuliXEx1
which would put this folder to the image path.

I am going to use addImagePath to add UserLibForSikuliXEx1.sikuli to the image path.

Still, I understand only half.
In the related bugs ,I explaned situation that make Sikuli-IDE aborted.
But in another situation, error does not occur.
For examle,

(1)open file [robot_CalcDemoEx1.sikuli]
(2)run [robot_CalcDemoEx1.sikuli]

I wonder why error doesn't occur in this case.

ok, I will try to back-track your approach the next days to find out, what might go wrong.
