next gen gallery thumbnail problem

since the site has a white background, a quick workaround could be to save the pngs as jpeg with white background?

this thread mentions a possible solution:

• wordpress dot org/support/topic/plugin-nextgen-gallery-problems-with-png-transparency-thumbnails?replies=9

this has an unpdated solution:

• wordpress dot org/support/topic/plugin-nextgen-gallery-png-thumbnails-with-transparancy-problem-1?replies=5

and this thread suggests saving as 24bit png’s rather than 8bit

ps cant post all links as dont have enough rep 🙁

if an admin can amend i’d be grateful
