imagestrip width and height

Hi !
Just a little newbie question about loadimage and an image strip...

i use 32px x 32px tiles.

1) i must use a 32px x 10 px png image as tileset.

2) i can use a 64px x 5 px png image, blitz go to the 'next line' for frame = 5.

Thanks !

It's OK to do either 1) or 2).

Thanks tonyg for the info !
