use .RegisterClientScriptBlock

ClientScriptManager cs = Page.ClientScript;
Type cstype = this.GetType();

if (!cs.IsClientScriptBlockRegistered(cstype, "script block name"))
{
    StringBuilder cstext2 = new StringBuilder();
    cstext2.Append("<script type=\"text/javascript\">");
    cstext2.Append("$('#image').attr('src','/new_image.png'); </");
    cstext2.Append("script>");
    cs.RegisterClientScriptBlock(cstype, "script block name", cstext2.ToString(), false);
