Few years ago (CMK 2.1, CMK 2.3, CMK 2.4), I have created my own icon (svg file) for Topics. Located in share/check_mk_web/htdocs/themes/facelift/images. It worked well.
Same action with CMK 2.5, my image is not recognized. How can I do for using it in my Topics?
Thanks.
Please note that this is the tab (and location) for the built-in icons. This could have worked before but it is not how it was intended.
Good news is: there is a special place for your custom icons. Please go to “Setup → Custom icons” or just move the file to htdocs/images/icons and you will be able to use it
