Can somebody help me?

On wii you have to load from the root directory. So load the image by "/apps/yourapp/pic.bmp" or possibly "sd:/apps/yourapp/pic.bmp". Or in the meantime you can just throw those pics in the root of your SD and it should work fine.

Ow ofcourse.. how stupid.. Thank you very much!

Also, I think HBC passes the CWD (current working directory) as argv - you could use that, in case the folder that your app launches from changes (i.e. someone renames the folder on SD card).
