Insertion Wizard divides the insertion process into a series of steps that
can vary depending on image type: assigning a color map, specifying a
correlation source, setting various positioning values, and transforming
coordinate systems. This method is recommended for new or intermediate
users.

Insertion Dialog provides the same functions as the Insertion Wizard, but
without the step-by-step process. You can change settings on the tabs of
the dialog box in any order, then apply them to the image. This method
is recommended for advanced users.

You can use Quick Insert to perform automatic correlation during image
insertion.

The Quick Insert option uses the correlation data stored with the image or in
an associated file. ProdNameShort searches for a correlation data source using
the following order:

1 Resource file

2 World file

3 Tab file

4 Image file

The highest order source is used to correlate the image after you click Open
on the Insert Image dialog box. If ProdNameShort cannot find correlation
data stored with the image, the image is inserted using the settings defined
on the 

 (page 351) tab of the Raster Design Options dialog box.

For example, geographical maps are often used not in true scale, but in 1:1
scale. With ProdNameShort you can set the default value of the insertion point
to 0,0, the scale to 1:1, and the rotation to 0, then use the Quick Insert method
to make insertion quicker and more efficient.
