You can import a picture of the drill core (or any other image file) in the log pane either using File | Import, or using a graphic log.

If you only have a few photos, the simplest method is to simply import the image(s). Go to File | Import, draw a rectangle around where you want the image to be placed in the log pane, select the desired image in the Import dialog and click Open. The image is imported. You can move it around or resize it in the log pane to exactly what you want.

If you have multiple images that you want displayed in exactly specific depth intervals (ie. photos of core or rock samples), you can use a graphic log. This log type is based on intervals, so the data must be saved in an interval table type. There must be To/From data specifying the depth interval in which the image should be displayed, and the file path to the image. You can either type in the file path (ie. c:\temp\well1.jpg) or you can right click over the cell and go to Get Image File Name from the pop-up menu and Browse to the image.
