Let's see how many wrong trees we can bark up <g>!
We really should do something about that STATUS ON situation. It seems to trip up most new users....

Martin,
Please try setting STATUS DEFAULT. In the past this has sometimes solved
this sort of problem -:)

The X coordinate of the upper-left corner of your raster image is 4,536,934 or 1,164 pixels (at 30 units per pixel) to the left. Is the image at least 1,164 pixels wide? If not, it won't show up. Likewise, the image needs to be at least 739 pixels high - the upper-left corner of the raster image is above and to the left of your map EXTENTs. Is that what you expect?

You need to have the geographic reference information to go with the TIF so MapServer knows how to locate it geographically. If you don't have such a file, you need one. If you do have such a file, could you post the contents? It's a six-line text file.
