Dataset with picture

I'm trying to store picture scanned into a dataset to send it into a crystal report, and finally saving it to a PDF.

The first part (Scan picture and storing into a picture array) is working fine.

What I want now is to put these picture into a dataset and send it as datasource to a crystal report.

does anyone know the type of data I need to assign to the attribute of the dataset for a picture ?

How do I have to transfer picture from my picture array into the dataset?

Thanks :confused:
