2D billboards appearing with clipped tops

Hi all, I have been trying to use a few free billboards that were downloadable and a few seem to do well with out any problems but then on others no particular size in mind just seem to have that flat cut off or clip as I call it. Can someone tell me what might cause this when constructing a billboard. Pointing me to any tutorials to make proper billboards would be much appreciated, I tried Google but haven’t had any luck with a good tutorial. There are a few youtube videos out there but most sound like the person talking has a mouth full of marbles and it get’s worse from there ;0) that loud obnoxious music just kills the learning mood.

Thanks in advance

would guess its a uv problem with the “bad” billboards…but why d/l anything blender has a addon called “import image as plane”
probably need to turn it on in user preffs then its under add mesh

Thank you, I will look into this feature of blender and give it a try.
