IFRAME with a Report with a Chart

I have an aplication in which i want to use reports. I want to display the reports in a IFRAME, so I just put them in a single way:

<IFRAME width=100% height=480px name=I1 marginWidth=1 marginHeight=0
src="http://localhost/ReportServer?/Remedy/incidencias_por_dominio&Fecha_Inicio=01/01/2006&Fecha_Fin=01/01/2007&rs:ClearSession=true&rs:Format=HTML4.0&rs:Command=Render&rc:Area=Report&rc:LinkTarget=_top&rc:JavaScript=True&rc:Toolbar=False" frameBorder=0 allowTransparency scroll=auto>

And in fact works OK, but then to publish it, i have to change the localhost by the quality server, so I do:

<IFRAME width=100% height=480px name=I1 marginWidth=1 marginHeight=0
src="http://10.y.y.yy/ReportServer?/Remedy/incidencias_por_dominio&Fecha_Inicio=01/01/2006&Fecha_Fin=01/01/2007&rs:ClearSession=true&rs:Format=HTML4.0&rs:Command=Render&rc:Area=Report&rc:LinkTarget=_top&rc:JavaScript=True&rc:Toolbar=False" frameBorder=0 allowTransparency scroll=auto>

AND it does NOT show me the chart i had and the embeded or project images (it shows me the tabular results or labels, only), in fact I saw if i put instead of localhost, the ip of my computer, it comes the same, how can i solve this???

Thanks
