Dinamic images

[Damir]

Please I need help and dont know where to post the question.....
So I am making a small asp.net application and need to generate a crystal
report with one image that changes depending of some data.
I am using a Oracle database and for me is not important if the images are
on the hard drive or in the database... I just dont know how ti implement a
image that changes in the crystal report

Thanks in advance... kindly regards
