If the total number of images is quite small (for example, less than 15) then you could add many Image/ActiveX Bound Control's to your report - 1 for each image.
Place these all on top of each other.
In the Print When... dialog enter har1="C" etc. in the Print only when expression is true field.

If you have a large number of images, you might want to try using only one image control, and use a dynamic picture source (maybe a macro substitution, though I am not sure this is possible), or use a static file name for the picture source and overwrite the file with the desired image for each label (by calling a UDF). This will probably mean that you will need to use the appropriate CLEAR command, because VFP caches the image.
