To finally display the image overlay on the client it is necessary to put it right into the application's infrastructure.
# Open the according [[CONTEXT]] in the ''[[Relation Editor | Relation Editor]]''
# Add overlay per drag and drop to ''"Infrastructre objects"'' ([[SYSREL INFRASTRUCTURE|SYSREL INFRASTRUCTURE]])
# Save the object with {{key press|Ctrl|S}}
The image map overlay has been added to your application.
