It's because you're loading the bitmap number as 0, and the bitmap 0 is reserved for the screen.

Also the bitmaps can only be .bmp files.

Ok, I changed it to a bmp. file, and I putted the bitmap number as 1, but now the bitmap wont appear on the screen, it just appear as a black screen. =/

Why does that happen?

You have to display the bitmap on the screen.

There are many ways to do it.
The easiest in my opinion is to turn it into a sprite, because you have a lot more freedom.

You can also turn it into a normal image and use the PASTE IMAGE command.

Or you can use the COPY BITMAP command and copy it to bitmap 0.

U know i made those 3 things u told me before, I kinda liked to make it into a sprite, but the only problem was that it appeared first than the other ones, so u couldnt see the other sprites, is there any command or code to see that sprite in the back, and the others in the front? Ty

Actually, Load Bitmap is misleading because 'Bitmap' in DB should be read as 'screen'.

There are 32 screens - 0 is the one you see and the other 31 are hidden. You can load an image containing multiple graphics into one of these screens and cut sections from it without the user seeing it.

Another use is with Create Bitmap and building up a screen unseen by the user - when finished, you copy it to the visible screen (0).

Unless you need to do either of these things, (or have another unavoidable reason), don't use Load Bitmap, use Load Image instead.

Load Bitmap, unlike Load Image, doesn't actually store the image anywhere for re-use. Clear the screen after Load Bitmap and you have to re-load it to see it again. Load Image on the other hand lets you use Paste Image as many times as you like afterwards.

So, loading a bitmap and then grabbing a single image is a waste of time when Load Image does the job in a single step.
