have you put a "set image colorkey" in the code to specify which color you want transparent?

I assume you are billboarding

draw the tree with a PURE black background red=0,blue=0,green=0
load it as an image with the extension 1, eg:

load image "tree.bmp",1,1 <<< this extra 1 stops the image being blurred

texture your plain object with it, eg

texture object 1,1

then just make the object use transparency

set object transparency objnum,1 <<< the one turns on the transparency

Daemons set image colorkey is a more advanced command when you want to use some colour other than black for the transparent part of the texture.

works here as long as you use .bmp, the .png image doesn`t work, so don`t use it, once the image is loaded a .png takes as much memory as a .bmp, so you don`t save memory using a .png anyway, just load it into paint and save it back out as .bmp , the texture doesn`t quite fit properly though, you can see some cropping around the edges, but other than that it is transparent, in your code you don`t set the transparency as far as I can see, try this and use it as a template if it works, like I said, if you are using black as a transparent color then don`t use the colorkey command.
