The binary sequence for the image can't be safely stored in the XML file due it's text nature, so it's converted to a base64 string.
Yes, most browsers can show that kind of data; take a look into this question for more background: Embedding Base64 Images

I've got a raw image : either a Bitmap object, or a byte[]. How may I include it in my website (in an .cshtml file), without saving it on my computer ?
I'm using c#, and the project follow the MVC structure.
You can put the image in your html as a base64 string. However, You do need to know the mime-type of the image as well because that has to be prefixed to the string.
For example:
<img src="data:#mime;base64,#(Convert.ToBase64String(bytes))" />
As a rendered example, this will show a dot:
<img src="data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot" />
recently, I've been developing a website with .NET c# and I've been trying to display images via the imagepath in the db. It is currently working by this line of code.
return File(byte array, "image/jpeg");
The problem is that by this line of code the layout page is completely ignored as only the image with white background is shown. I need to display the image along with the return view (the image inside the layout of the website). thx
The reason you're not seeing anything is because you can only have one type of response per request; Either a response containing HTML or a response containing the image.
What you need to do in order to serve images via your application is set up a route that you can put in your <img> tags as the src attribute.
<img src="/static/images/123">
Your route would listen for requests on the /static/images/ path and then try to parse the ID number at the end. It could then take that ID number (123) and look up the relevant image in your database.
So, to be clear, you'd have at least two requests that occur; First, you serve the request for the page, then you serve subsequent requests for the image(s). These two request handlers do not share the same code.
Finally, if you really wanted to "inline" an image as part of the page response, The only way you can "inline" an image into a page is to base64 encode it and set that as as the src of an <img> tag. This process is slow and bloats your HTML, making it take longer to load.
In my C# code I am rendering a JPEG image of a HTML page using a string variable (which holds my html code). There's a table in that html code whose borders are not being rendered in JPEG image.
I am using the following code to generate image :-
string sHtml = m_Html; //m_Html contains the html code
Image img = HtmlRender.RenderToImage(sHtml);
After thorough searching, I understood that HtmlRenderer renders the string which we pass (as a parameter) into a HTML page and then takes a snapshot. Now, the rendering engine which HtmlRenderer uses is not very sophisticated, it does not support latest/complex CSS queries.So if you are facing this issue, use simple HTML/CSS.
If still you are not able to solve the issue, use a different library 'NReco'. NReco is open source if you just use it, licensed if you want to modify it. NReco is better than HTML Renderer.
Fairly straightforward question, I have images stored in my database as varbinary and would like to provide a link to these images rather than displaying them on the website. When a user clicks the link he/she should be able to download the image.
An image is served in response to a request.
<img src="?" /> <!-- what goes here? -->
You need to create an HTTP handler to receive requests for these images.
A handler is an executable available at a specific URL which can respond to your request; in this case, by serving the binary data of an image. An ASPX page is a valid handler, though there are more efficient handler types for images.
<img src="MyHandler.aspx?imageId=123" />
The handler should do a few things:
validate that the ID is valid and that the caller has permissions (if needed)
retrieve the image from the database
set appropriate response headers
use Response.BinaryWrite() to send the binar data to the client.
Note that if you are using ASP.Net MVC, you can use a controller as your handler.
An alternative method is to base 64 encode the bytes and embed them directly in the image tag.
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA

This is a useful technique for small images or when the expense of multiple requests is very high.
See: http://en.wikipedia.org/wiki/Data_URI_scheme

You should create a page that takes an image-id and returns the image.
You may consider this question:
Display image from a datatable in asp:image in code-behind
I had a similar problem an that answer solved my question. Beside that, you can use binaryimage component from Telerik:

I am working on an email client application in C#.
I want to display an html email on the page with embedded images.
Now, I use a div and set mail bodyhtml to div innerhtml property.
I have a problem with display embedded images.
I know everything about embedded images (content-type, name, content-id, base64string or byte[] as content)
I used image data uri, but unfortunately it is not too perfect, for example (ie8-32KB limitation).
I tried to ihttphandler as imagehandler, but it is not run on a simple postback, when I set div inner html.
I don't want to save these images on the server.
Any idea or suggestion?
Sorry, my english is not too good.
Thanks.
For doing this, you would need to do something like:
(In your .ashx file)
Response.ContentType = "image/png";
Response.BinaryWrite( <bytes> );
