* Is the file in the correct place?
* Is it actually a bmp file and not something else like png or gif?
* Can you open the bmp file with windows?
* Are you doing anything stupid in your code?
Post your code. There could be a million things wrong, and we have nothing to go with.
This is the code I'd use, provided the bmp file is in the same folder as your project.
rem load a bitmap
load image "myimage.bmp", 1
