Embedding an image in the html?

[David Thielen]

Hi;

Is there a way to embed images in the response rather than writing them to
disk and having an <img ...> tag? And if so, how is it done and what browsers
support it?

You are unclear about the actual problem.
It's easy to substitute the SRC="" behaviour in ASP.NET and simply stream an
image to the user.
The stream data is up top you.

Be clear..

yes, for browsers like mozilla, firefox, opera and safari that implement rfc
2397, you can include the image in as a base64 encoded. IE does not support
rfc 2397.

<img src="data:image/gif;base64,<base64 encoded image>">

Right - and that src="anotherasp/image.png" can be handled by me.

But I was wondering if I could add the image to the response that contains
the html - like a MIME email message. That way I don't have to track images
that will be requested shortly and also determine when to dispose of them.

Oh wow - this is great. Too bad IE doesn't do this also but we can work based
on browser type. By any chance do you know what version of each it is
supported in?

Is this for dynamically generated images (which evt. differ between users)?
Then i can imagne..

Hi Dave,

IMO, I don't quite recommend using the
<img src="data:image/gif;base64,<base64 encoded image>">

since it's not a standard feature in html, also making image binary mixed
with html content will cause the main page's size increase extremely.....
I'd suggest you consider building an ASP.NET httphandler which help
retrieving image stream from different soruce (database, file system, or
dynamically through GDI+ code) and write them out as a single image stream
... Thus, any other pages can use <img src=xxxx> to reference that
httphandler's url.... here is
#A simple ASP.NET photo album
