Framework Brl.Basic
Import Brl.System
Import Brl.GLMax2D
Import Pub.Libpng

Graphics 640,480

If LoadImage ("D:\Dev\BlitzMaxCore106\doc\bmax120.png") = Null
	Print "Your Imports are wrong"
Else
	Print "Your PNG image isn't correct."
End If

Incidently, the correct answer is: Your imports are wrong.

try :
Import BRL.Pngloader
instead of
Import pub.libpng

Well I tried both and neither worked.

FlameDuck:
I put that if-then statement and no errors came up so I know the image is loading, but not sure what else to make of it

flaith:
Also the import didn't change anything either :( EDIT: okay that fixed the LoadImage, but not the LoadAnimImages there is a major bug or something in BlitzMax if this happening

i tried that code :

Framework BRL.GLMax2D 
Import BRL.Basic
Import BRL.System
Import BRL.Pngloader

Graphics 640,480,0

Incbin "gfx/Pipe.png"
Incbin "gfx/Robi.png"

Const BOARD_WIDTH   = 33
Const BOARD_HEIGHT  = 33

'MASKBLEND marche mieux avec pipe_3 car les couleurs sont indéxées
'voir dans Gimp différence entre le pipe.png et le pipe_3.png

SetMaskColor 255,0,255
Global pipe:TImage = LoadAnimImage ("incbin::gfx/Pipe.png" ,BOARD_WIDTH, BOARD_HEIGHT,0,17,MASKEDIMAGE)
Global robi:TImage = LoadAnimImage ("incbin::gfx/Robi.png" ,BOARD_WIDTH, BOARD_HEIGHT,0,8,MASKEDIMAGE)

SetClsColor 128,128,128
While Not KeyHit(KEY_ESCAPE)
	Cls
	For Local i = 0 To 8
		DrawImage pipe,10,50+(i*33),i
	Next
	Flip
Wend

An error isn't SUPPOSED to come up. It's supposed to print "There is a problem with your imports" in the console. And it does, because there is a problem with your imports.

Also the import didn't change anything either :( EDIT: okay that fixed the LoadImage, but not the LoadAnimImages there is a major bug or something in BlitzMax if this happening

It is not a major bug in BlitzMAX (or any bug at that). Remove all your import and framework statements and it'll work fine, because it's a problem with your imports.
