Help with raster ortho photos

We have parcel maps that are in state plane coordinates and ortho photos that are .tif files and these files have a corresponding .tfw file that is an ascii file with what looks like the following: 2.0000000000 0.0000000000 0.0000000000 -2.00000000001905682265597The last two lines must be state plane coordinates for insertion and the first four lines must be something to do with scaling. When these two files (the tiff and tfw) are bought into ACAD Map, the raster image fits the parcel drawing for the same area. But in ICAD if you insert the raster image, and not knowing what to do with the .tfw file, the raster image comes in way off and at the wrong scale. Does anyone know how to use this .tfw file with the image insert command.Using ICAD 2.2.0025 with raster image optionThanks for any help I can getBryan Thorp

    Nevermind, I tried it again today and lo and behold there is a toggle for a position file and once this is on the .tfw file is found and used.
