Images and rollovers in Opera Answered
Images often do not work in Opera, the little inline galleries per instructable don't work (can't click on images), and rollover tooltips for images don't work. JS error is thrown:
message: Statement on line 3: Undefined variable: HelpBubble
Line 3 of inline#12 script in https://www.instructables.com/id/SRLH6Q1FK75CZBS/
Not sure about the gallery clickables, might be due to the erroring inline script.
