Hey Taz, you dont need to use all the applications that are on windows on the linux box. There are plenty of applications which can do the same job natively in linux. For instance, for Irfanview in Windows, there exists a Gwenview in Linux. Well there are many more but I'd like to know which desktop manager you are using.. Gnome or KDE, then I guess I can give u more examples.
Regarding Acerose. I tried to install it myself, I think its not supported by wine yet and so the errors. In anycase.. you can give a try to KDEwallet, which I think is a similar application.
Glad to have you on LinuxQuestions
