how to set any image on workitem editor?
One answer
The question is very fuzzy and does not really provide good information about what is asked. Based on my best guess, I assume you want to show an image on a work item e.g. where an attribute editor presentation is located. Here my thoughts:
The only way of doing this in general, and show the image is explained in https://jazz.net/library/article/1093 Lab 5 displaying the workflow state.
If this is only needed in the Web UI, you could have a look at https://github.com/jazz-community/rtc-statushistory-presentation, maybe there is a way to display images using some kind of extension. One alternative could be a custom editor presentation. https://jazz.net/wiki/bin/view/Main/ContributingAttributePresentationsV2 I have stayed away from this so far.
