If your map doesn't have any outdoor areas that need a sky, setting "sky" to "none" in the map editor should stop the black transparency. Otherwise, you would need to edit the black in the image's palette to off-black (ie RGB = 8 etc). You can usually do that in a photo editor with something like a "color replacer" or "palette edit" tool.
The black transparency is a built in texture masking feature, but it does tend to get in the way.
