Just include the path to the file you want relative to the .exe.
If your .exe is "G:\KamenRiders\KamenRiders.exe" and your image is "G:\KamenRiders\OOORedCombo.png", you can just do this:
load image "OOORedCombo.png", 1
If your .exe is "G:\KamenRiders\KamenRiders.exe" and your image is "G:\KamenRiders\Media\Images\OOORedCombo.png", you can just do this:
load image "Media\Images\OOORedCombo.png", 1
It won't matter where the user puts your game, as long as they keep all of its files together.
Quote: "to IanM... okay, i will remember that with the link... but will it works on the someone-else computer that does not have plug-in?"
When you use the plug-in, it'll be included in your .exe file automatically.
