XnView Software

Hello.
Skipping existing files takes just a little to long when batch converting.
I think they're being loaded and only after xnview check is a file already exists.
When converting hundreds of big files it can take a while.

Hello.
Is it possible to define the background color when converting a png file with transparency to jpg?
The final jps always gets a white background although I defined "Background color" in the batch convert settings of xnviewMP.
Is there a way to accomplish this?
Thanks
