.NET Forum / ASP.NET / General / February 2008images not showing on dev-machine
I'm developping a web-app using VS2008 (Pro edition) on a Vista Ultimate machine . For some reason images aren't shown, the only thing shown is the little square with the circel, triangle and square in it. Even if I set the ImageURL property in my Page_Load and set it to the absolute path of the image, it doesn't show. I have also tried using '~/Images/58.jpg' '/Images/58.jpg' 'Images/58.jpg' but still the same result. It's real annoying if something this simple just won't work. Has anyone encountered this and maybe have some sort of solution for it ? TIA, Jurjen.

Ensure that images are appropriately stored and accessible when you type the full url in the address bar, e.g. http://localhost/Images/58.jpg (if site is located under root) if images are there but you can't see them, it could be a permissions issue, or a format problem Does the account ASP.NET runs as have file permissions to access the images ?

[quoted text clipped - 10 lines] > TIA, > Jurjen. I have taken your advice and found out that my ASPNET account is actually NT AUTHORITY\NETWORK SERVICE. I have granted this user rights for the Image folder, but the pictures aren't shown. I've granted this user rights from the root level of my development folder but still the pictures don't show up in the page. I've also tried accessing Image-files through System.IO and reading the content into a string and that works just fine, so I guess access-rights are configured ok. I'm a little lost as to what to do next. Jurjen. > I'm developping a web-app using VS2008 (Pro edition) on a Vista Ultimate > machine [quoted text clipped - 13 lines] > TIA, > Jurjen. If the ASP.NET account has the necessary permissions, it's likely that you have a problem in your code. Can you post the code you use to access the image files ? Juan T.

Juan, It's just a very straightforward simple test-page so here it comes. There's no code in the code-behind. The weird thing is that the first and second image don't show in the (vs2008) Designer, but the other 5 do show just fine. When running the page they are not visible. Here's the code I used to access an image file, just to make sure that the 'ASPNET' could : String FileName = MapPath("~/Images/58.jpg"); System.IO.StreamReader sr = new System.IO.StreamReader(FileName ); String Content = sr.ReadToEnd(); sr.Close(); thanks for your effort, Jurjen. <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TestPage.aspx.cs" Inherits="<namespace>.WebApplication.TestPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <div> <asp:TextBox ID="TextBox1" runat="server" Text="BZP" /> <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" /> <br /> <br /> <asp:Button ID="Button2" runat="server" Text="WebServiceTEst" Visible="True" onclick="Button2_Click" /> </div> <img src="/Images/58.jpg" alt="Test " /> <img src="~/Images/58.jpg" alt="Test 2" /> <img src="Images/58.jpg" alt="Test 3" /> <img src="Images/57.gif" alt="Test 4" /> <img src="C:\<ProjectLocation>\Images\57.gif" alt="Test 5" /> <asp:Image ID="test" runat="server" ImageUrl="~/Images/58.jpg" /> <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/57.gif" /> </form> </body> </html> > If the ASP.NET account has the necessary permissions, > it's likely that you have a problem in your code.

Binary read is working. On Jan 14, 9:24 pm, "Jurjen de Groot" <Jurjen.de.Gr...@xs4all.nl> wrote: > the first and second image don't show in the > (vs2008) Designer, but the other 5 do show just fine.

If the format of the file is correct (it's not a text, or any other file saved with the .jpg extension) and you can open it in Paint, or Photoshop, but not in the browser, then it could be a format problem. There are some situations when browsers (at least IE and FF) cannot show some jpeg files, if I'm not wrong, in CMYK encoding. In this case you can save file in RGB to see if this helps. Now that the app is running in test in the field, the images are shown just fine. It's just really strange that when running local there's problem with this. Thanks for all your help on this.

Try going into IIS Manager and for your Default Web Site set the Home Directory to the path on disk where your website resides. For me it is C:\Development\Project23.net (my current web project). That will upset some other programs that do web demos on your local machine, like some 3rd party controls that demonstrate their stuff using the local web server and expect C:\inetpub\wwwroot to be your home directory, but you can change it back and forth as needed. It works well for me and allows me to test and debug my projects as if they were on the production server. > Now that the app is running in test in the field, the images are shown > just fine.
