Why does my localhost image url change - asp.net

I have a bunch of images in my localhost folder (C:\inetpub\wwwroot\Images) which I am trying to access within my ASP.net application. The image src generated in my markup is:
<img id="MainContent_MainImage" src="localhost/Images/FGOStuart_7166.jpg" />`
This fails to load the image and if I look at the source for the page it actually directs to
http://localhost:64395/Pages/localhost/Images/FGOStuart_7166.jpg
so it looks like it is trying to access a path relative to the page (on the Pages folder). The src works if I type it into the browser manually and the image is displayed.
Can anyone explain what's going on here and how to fix it? I'm attempting to move the images out of the database and onto the file system but without much luck so far.

That's because the browser assumes "localhost" is a folder and adds it to the current relative path. Add http to it and it should work fine, or remove localhost altogether and just leave the /Images... part.

Try it like this:
<img id="MainContent_MainImage" src="~/Images/FGOStuart_7166.jpg"
alt="An Image" runat="server" />
This resolves it server-side from the root down. And always use an alt :)

What you really want to be doing is using the magic tilde:
<img id="MainContent_MainImage" runat="server" src="~/Images/FGOStuart_7166.jpg" />
~ signifies the root of the application. Notice I added runat="server", too.

CSS and image paths not working

Paths defined within master files are not working on a new server. They worked fine on production server and development machine. Here is an example of the file:
/HeadOffice/Styles/HeadOfficeCalendar.css
Unless I put full URL with the virtual name, the paths don't work.
working:
https://connect.server.co.uk/FesQA/HeadOffice/Styles/HeadOfficeCalendar.css
I can also include resolved URL within ASP>NET code tags but I don't want to change all those paths they are probably hundreds of them. so if the head office folder is in the same folder as master file it should just be able to reference like:
/HeadOffice/Styles/HeadOfficeCalendar.css
It seems the references within the master files and aspx files seems to work fine by adding ~ and runat = server. but images references within the CSS files are not working unless I include the full path.
DOESN'T WORK
url(/HeadOffice/Images/tlcorner.png)
DOES WORK
url(connect.server.co.uk/FesQA/HeadOffice/Images/tlcorner.png)
I know I've answered this before, but this has been known issue forever in VS.
Simple way to do this correctly is to drag the CSS file from Solution Explorer window to head section of master page in code view.
For other links on your site, make sure to include the runat="server" attribute and resolve your links like this (with "~" operator):
<img src="~/images/sample.jpg" runat="server" />

Images not appearing in Joomla template

I'm new to Joomla, but I've followed few tutorials. I've created a template for my website, but no images are showing up. Looking to the source, my image references look like:
<img src="/templates/fiziaimages/zdjecieDol.png" />
When they should be looking like:
<img src="/templates/fizia/images/zdjecieDol.png" />
^
fizia/images is the correct directory, so I don't know what causes the backslash to not appear.
in a first time you can use your browser inspector to verify if your images are really found.
If it's ok you can try to put your images in the "image" directory in the root of your website

Umbraco not allowing httphandler resized image to be input

I am attempting to move legacy content into Umbraco v4.9.1. Some of the photos that are being migrated are being resized using an httphandler (ImageResizer.ashx) using variables passed through the query. When I attempt to save the path the url is replaced with either "/" or what the path originally was. Is there a work around? The tag is below.
<img src="/imageresizer.ashx?mw=232&src=/imagePath/image.jpg" />
The url is correct, because if I type it into a browser the image comes up fine. It seems like Umbraco is filtering out this url.
UPDATE:
I am noticing that the editor is chopping off everything before /imagePath/image.jpg and only displaying that. I have tried turning off the TidyEditorContent in the UmbracoSettings.config and it still does this.
A workaround would be to UrlEncode the src part of these Urls, where "/" is replaced by "%2F".
<img src="/imageresizer.ashx?mw=232&src=%2FimagePath%2Fimage.jpg" />
I don't know if you can do this is your particular situation, but it is a workaround.

Relative paths of images contained in an ajax aspx page

In my webapp, I have a folder Views. In this folder several .aspx pages live. I don't use the rendered contents directly in the webapp, rather I request the contents using ajax in a main aspx page on the root of the webapp.
Now when I refer to an image, "images/image.png" will work since the image reference lives in the aspx page on the root. When I change this to "/images/image.png", this won't work since the root is determined by the virtual IIS folder.
How can I have a clean reference e.g. "/images/image.png"?
Firstly and probably most elegant, make the element run at the server and use the root-reletive url:
<img src="~/images/image.png" alt="image" runat="server" />
This will automatically translate your src-value into a path which will resolve from your current location. However, there is one caveat. If you do it on pages which are included, asp.net may create an incorrect value here, as it could be morphed into
<img src="../images/image.png" alt="image" />
if you are a directory down. So if you include this result in a page in the application root folder, your value may not be correct. I have not seen a good way to work around this. It will, however, show you a warning if the file doesn't exist.
Alternatively, you may want to manually set the root path for such pages:
<img src="<%=Request.ApplicationPath %>/images/image.png" alt="image" />
which will transform into a path always coming from the root of the site:
<img src="/AppPath/images/image.png" alt="image" />
Obviously, this is a bit more verbose. Additionally, you will not be able to see any warnings if the referenced file does not exist, as it will be dynamically built.

<img> tag in masterpage does not show logo when called from IIS virtual folder?

It works fine when I dont use virtual folder. My virtual folder is named test which points to an application inside MyDocuments. The path to my App is
localhost\test\app\login.aspx
Note that if I move the application in the root folder wwwroot and make it an application, it works fine. I tried
<img src="logo.jpg" />
<img src="..\logo.jpg" />
<img src="~/logo.jpg" />
<img src="\\test\logo.jpg" />
Can it be fixed or should I leave it? My logo.img is in root folder of the application. I move it to \images\ folder as well still does not work.
There is a similar post here Relative Path in master page for img tag which did not solve my problem because it does not use Virtual Folder path.
Edit: I did used tag also and it did not work too.
<asp:Image ID="imgLogo" runat="server" ImageUrl="~/logo.jpg" />
Thanks in advance
Try adding runat="server" within the your html img contrl and select the src="" from the intellisense property of the visual studio.
or
Use Asp image server control instead of html img control and set the imageurl attribute from intellisense property of the visual studio.
Hope this will help you...
Use the asp:Image, it does all the hard work for you and gets rid of this kind of problem.
The ~/logo.jpg syntax only works in server controls, such as <asp:Image />. The ~ is then a shorthand for the root of your web-application.
If your 'test' directory is an application, then the logo should be there to be found.
To troubleshoot these kind of problems, you need to know the mapping between the physical location of your page ('login.aspx') and the url used to call it. A similar mapping will exist between the physical location of your image and the url you need to get it.
You could try to enter the url for that image directly in the browser. When you have a url that succeeds, you can figure out how to refer to that image from your page.
If it's in the same directory, a plain 'logo.jpg' will work. If elsewhere, you need to add some folderpaths ('images/logo.jpg' if it's in a folder named 'images' next to that page).
I had the same problem and above solutions worked for me.
I know this is old post.
In Masterpage all you have to do is
drag and drop Image
then go its properties and set the url (You can browse it from there)
Now all my pages have the logo with no issue of finding it.
