si, ho fatto una prova con un repeater
<marquee behavior="scroll" direction="right" height="130" width="485" scrollamount="2"
scrolldelay="80" truespeed="true" onmouseover="this.stop()" onmouseout="this.start()"
style="text-align: center; color: #000000; font-weight: normal; font-size: 10px\;">
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:Image ID="imgEmpl" runat="server" ImageUrl='<%# Eval("PhotoPath") %>' />
</ItemTemplate>
</asp:Repeater>
</marquee>
