Each '..' moves up one folder. So if your path is:"POOA/vcproj/holy/debug/game.exe"
And you want to get to:"POOA/data/tiles.png"
(one '..' for each of: "vcproj/holy/debug")
However, more practically, your game isn't always going to be in the debug folder. If you release your games to other people, you'll more likely not want it in a folder labeled "debug".
So, you should tell Visual Studio to output the generated executable into a folder more to your liking. I suggest a 'bin' folder, right next to the 'data' and 'src' folders, as it is commonly named 'bin' (for 'binaries', which is what .exes and .DLLs are).
Once you tell Visual Studio to always put the executable in your 'bin' folder, each time you compile your project it will end up there. Then your path would just be "../data/tiles.png"
I don't use Visual Studio personally, so I can't tell you how to redirect the exe to a different folder, but I'm sure it can do it (most IDEs can).
