Hi, I am havig problem trying to load an image in my aplication,
my proyect path is:
C:\Archivos de programa\Research In Motion\BlackBerry JDE 4.7.0\bin\MMedios\multimedios.java
\img\rainbow.png
the .png image doesn't have anything wrong, it was taken from a example package, and was used in the example code, and worked fine (the example aplication was build correctly, ant the simulator loaded the .png image.
in the debuger says tha the img variable is null.
thanks in advance for your help.
