change images in runtime crystal report

[srdva59]

hi,
i have a report and is working with .net
now i need
load images in runtime by passing the values in .net or load the image by db
the control that i using is
the crystal report viewer, i have found codes in the web that refer this:

"crxReport.Sections(3)"
"CrReport.Sections("Details").ReportObjects("Picture1")=? "

but with the control what i using i dont have that option
what is the control that i need load to the project that have that options?
or is some especial version of crystal report?
thanks for your help
