I've encountered another problem here, it's not specifically about Heroes, but it does relate to it.
In Photoshop, for the main hero image, I initially set:
Width: 128 pixels
Height: 128 pixels
Resolution: 128 pixels/inch
Colors: RGB 32-bit
Is this correct? Please advise if I'm wrong.
And how do I save my creation in TGA format?

Please, explain it to me or point me to the relevant post in another thread.
