Dear Liang
nether heard about similar demand. Without knowledgde: what is the purpose of the picture in the EHS maintenance process, no real help is possible. (e.g. should picture be printed in WWI report etc.)
If you check deep the EHS customizing you will see. you can "hide" if needed the Tabs as shown; Not checked: but using customer development you may add "Tabs" to "do something".
