Please use always latest IrfanView version and latest language versions.
A huge THANKS to all users/translators sending me new languages and updates!
If you want to translate IrfanView to another languages, download the language SDK:
Server 1, Server 2
Please check "README.TXT" file. You need "Microsoft Visual C++" or a tool like "RisohEditor" or "Resource Hacker" for translation.
