I don't think you can do this in a single row, although you can do it in a column. Some of this depends on how your data is set up. If you have one record for each picture, you definitely can't do it in a row. If you have a single record with a field for each picture (NOT good db design!) then you could. In this case you would put a suppression formula on the image object that is something like: IsNull({field for this picture})
You can either store the pics in the database or put them in the file system someplace and store the path and filename in the database.
If you store them in the file system, use the properties of the image object in the report to set the image based on the value in the field.
If you store the pics in the database, they have to be in JPEG format and you need to either use a native database connection or an OLEDB connection - I've not had much luck getting this to work with an ODBC connection.
