Web Forms :: Listing Files Inside A Directory, Iis7 Forcing 404?

I have some issues regarding listing images from inside a directory. What I want to do is to create a Default.aspx page that will search and list the images located inside a folder of my website (where I simply drop them in it). I tried with a treeview, DirectoryInfo and both worked when I compiled my website with visual studio, but when I access them via another computer, I get a 404 for the page. My bet is that iis7 is blocking my code from accessing the folder containing the images. Any idea of how to fix this and make it work ?the code I use to browse in my image folder

string path = AppDomain.CurrentDomain.BaseDirectory;
DirectoryInfo diFiles = new DirectoryInfo(AppDomain.CurrentDomain.BaseDirectory + @"contentmiscimages");
foreach (var f in diFiles.GetFiles("*.jpg"))
{
Lit.Text += "<a href="" + f + ""rel="lightbox[img]" title=" + f + ">" + f + "</a>" + "<br />"; //I format the image as an url inside a literal
}
