Ah ok I understand your question now.

Basically you want to check if there's a collision, then check where the ball is during that collision in relation to the brick. 

If IMAGESCOLLIDE(image,x,y,frame,ball,bx,by,bframe)
  If bx<=x or bx>=x+IMAGEWIDTH(image)  ;if its outside the brick's x
      speedx=speedx*-1
  Endif
  If by<=y or by>=y+IMAGEWIDTH(image)  ;if its above or under
      speedy=speedy*-1
  Endif
Endif


Thats what I would try. This is assuming that your ball is midhandled and the bricks are handled at 0,0.
