XnView Software

Can I ask XnView would improve archive support addon in the future ? I really like XnView and really need this addon

I found it. But when using it, I open first picture in a *.rar file, when I switch to next pictures, it show strange pictures which I don't know where are they

Can XnView open pictures in *.rar files ? It can open *.zip files but sometime it have error "Format of the file *.zip/rar could not be determined"
