I have code that's pulling some images from a document library. When I'm logged in and testing everything works just fine but when it's published it forces a log in screen.

Here's the kicker: if I reference the images through normal HTML, the published page doesn't require a login. It's only when I try to pull the images in and build a list of them into an asp:literal control.

The permissions on the list allow anonymous read, as far as I can tell. Something is fishy somewhere. Please help!

Below is the code I'm using:

 public void GetBanners() {

string strCode = "";

using (SPSite oSite = SPContext.Current.Site) {

    SPList oList = oSite.AllWebs[0].Lists["MainPage Banner Library"];
    SPView lv = oList.Views["All Pictures"];
    SPListItemCollection lic = oList.GetItems(lv);

    foreach (SPListItem li in lic) {
        if(li["Enabled"] is bool && (bool)li["Enabled"] == true) {
            if(li["URL"] is string && li["URL"].ToString() != "") {
                strCode = strCode   "<a href=\""   GetURL(li["URL"].ToString())   "\" target=\"_blank\"><img src=\"/MainPage Banner Library/"   li["Name"].ToString()   "\" alt=\" \" /></a>";
            } else {
                strCode = strCode   "<img src=\"/MainPage Banner Library/"   li["Name"].ToString()   "\" alt=\" \" />";
            }

        }
    }   
}
ltBanners.Text = strCode;
}
