Need to remove html editor from the service catalog variable

I need to remove the html editor when the variable is displayed. I am displaying a picture which is stored in a HTML variable. The issue is that it works fine but also diplays an HTML toolbar.

Please let me know how shall I remove this HTML toolbar. I the variable read only but still it shows the toolbar.

I have taken the type as HTML and running the default HTML code to show the picture.

I have tried the codes provided in this community but it doesnt work for me. I am using both the google chrome and internet explorer. 

I saw in community and think there needs to be a class name to be disabled but how to find the exact code for that which needs to be put in the onLoad client script

Please help as this is real urgent issue for me
