I can't lose the white border in Opus image viewer. I've unchecked this: 'wrap around picture lists' but doesn't change anything..??
Wrap around picture lists, as the manual says, is to toggle whether the viewer has a 'start/end' when viewing a generated list of pictures. Nothing to do with the background of the viewer.
You can change the colour of the viewer background with the preferences below that option. If you auto-size the viewer to 'fit every picture there won't be a background image shown.
Turn off the Frame picture option in Preferences.
Oh - you're talking about the frame - not the background colour....
Oh sorry, I'm being stupid again,,Frame picture was checked...Unchecked it. No border now...Thanks
