I use Honeyview portable to watch archived image. it works ok with rar / zip but not 7zip files. It can read 7zip files but the process takes too long, and it caused freezing on my intel i5 gen 6 laptop. so i need to extract the 7zip files and compressed again into rar files.I'm using MangaMeeya CE for archived images browsing, it didn't work on these files, then I found out these are actually JPEG files, why he named them in png format, clueless.
