Okay, I need help...I don't know how to draw an image at the mouse's coords...How do I do it?And one more thing...
this is for a game, I need to test if the mouse image and button collide, I think you do it like this:

If ImagesOverlap(mouseimage,mousex,mousey,button,320,30)
if mousehit(1)
;do something
endif
endif

but, of course, that doesnt work because the image doesnt move with the mouse!
I do the image drawing like this:
[code]
drawimage mouseimage,mousex,mousey

If ImagesOverlap(mouseimage,mousex(),mousey(),button,320,30

you need the parenthesis or MouseX and MouseY will return 0.
Like this

Print MouseX()
Print MouseY()

It's because it's a function and returns data, the data being the mouse co-ord on the x or y axis.

To get any command/function to return a value in any version of Blitz you always need brackets ().
