Hello Drat,
you've optimized Image:Sopwith-screenshot.png in the past. Whenever you optimize images you should use the -o7 parameter for the best results - that way the size of the file could be reduced even further (by 25.23%). Be also sure to use the lastest version, available from here.

- Actually, I do use the -o7 parameter. But thanks for the heads-up regarding the latest version! By the way, for convenience, I use a batchfile that makes a copy of a file with the file extension ".pngo", which is associated with another batchfile that runs the image through OptiPNG. Saves a lot of time through lessened fiddling around, and retains the original.--Drat (Talk) 13:55, 25 May 2006 (UTC)
- Why don't you use the -k parameter instead? (a .png.bak backup and an optimized .png file are the result) --elias.hc 14:13, 25 May 2006 (UTC)
- I'll try that. I'm sure there was a good reason I didn't before, but I can't recall it at the moment.--Drat (Talk) 14:18, 25 May 2006 (UTC)
