OnLoad represents a server-side function, not a client-side JS. So, make sure
you have defined the function in question in the code-behind of your page.

Actually I need to know how to make it run client side

I deleted some comments when I posed this and must have deleted the line I
added below

Should I be using jscript or JavaScript

thanks

<script type="text/JavaScript" language="JavaScript">

On the server side: Image1.Attributes.Add ("onclick", "resizeImg('" +
Image1.ClientID + "')");

Also, modify resizeImg() JS function to include the following as the first
line (before var p = o.parentElement):

var o = document.getElementById(o);

Image1.ClientID + "')");

I don't know where to put the above.

Thanks for helping

I did this and at least do not get any new errors - but I still get:
'resizeImg' is not a member of 'ASP._default_master'

thanks again

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.Load

Image1.Attributes.Add("onclick", "resizeImg('" + Image1.ClientID + "')")

End Sub

and

<script language="JavaScript" type="text/JavaScript">

function resizeImg(o) {

var o = document.getElementById(o);

var p=o.parentElement;

if ((o.clientWidth/o.clientHeight)>(p.clientWidth/p.clientHeight))

{o.style.width='100%';o.style.height=''}

else

{o.style.width='';o.style.height='100%'}

}

--%> </script>

and

<asp:TableCell runat="server" ID="TableCellR4C1" Height="300"
BorderStyle="Groove">

<asp:Image ID="Image1" runat="server" AlternateText="Alternate Image"
Height="100%"

ImageAlign="Middle" ImageUrl="~/Images/churchdefault.jpg" OnLoad="resizeImg"

Width="100%" />

</asp:TableCell>
