Hi this is irfan, and i live in marmaris/turkey..i am working in tech branch since 1999.working as comp. technical support. designing and programming web pages, also learning desktop programming nowadays..hope to see you around tech guys.
IrfanView is an extremely popular freeware image manipulation tool. (but not open source, my mistake)
i particularly love it because it has a really great command line interface and non-lossy JPG rotation. it's really good for calling in your own applications. if you do any image manipulation, especially in a batch mode, this is a must-have
anyhow, you have the same name as the developer. that is all. :)
