HTML / ASPX image

[tma]

I have the following HTML in use on my web page. I need it to show a graphic
image on the page but do not know what to use in the codebehind to make the
graphic appear. If I load the source url in a browser by itself, the graphic
appears, but when I use the tag in a web page it does not. Anyone have a
suggestion for VB?

<img
src='http://www.domain.com/MohawkWS/MohawkHitCounte r.aspx?ItemID=7 103830413'

I'm under the impression that the src element of the <img tab needs to point
to either a .gif file or a .jpg file, not to the httpresponse of a aspx
page.

Hi,

The img control loads a graphic, you are loading an ASPX page. To do what
you are doing create a user control and then use that in your page.

Creating a user control:

Adding a user control:

Good luck! Ken.

Well, you're under the wrong impression. An ASPX page can indeed serve an
image, and can indeed be used in an image tag.

I check out the URL you posted: no image. Did you swap out the real URL for
a fake one? It's kind of hard to help in that case. Can you post the real
URL? The first thing I want to make sure of is that the page is really
returning an image. It may be returning HTML that contains an image tag,
wich would be wrong. Can't tell without the URL.

This method should work. It's not required to use the "correct" extension
as others suggested, as long as you set the correct contenttype
(image/gif, image/jpeg, ..). See Response.Conten tType.

Did something go wrong with the post? I noticed that you seemed to have
no space before "border" and no value for "alt".

Hi Kevin,

This is good to know. How do you return an image or maybe other type of
file from an ASPX page? The reason I'm asking is that Forms Authentication
seems to only protect ASPX pages and using this it could be used to force
people to log in who are trying to go directly to something other than an
ASPX page. Thanks! Ken.

Hi Ken,

file from an ASPX page?
An ASPX Page class is an HttpHandler. It handles HTTP requests. It can
therefore handle a request for an image. The page gets the image in one of a
large variety of ways (builds it, fetches it, etc), sets the
Response.Conten tType to "image/jpg" (or whatever MIME type you are working
with), and then saves the image to the Response.Output Stream. You can then
reference the page in an image tag. Example:

<img src="image.aspx ?modificationPa rameter=value">

Note that, since it is an ASPX page, you can pass additional data to it via
the QueryString, for modifying the image, or whatever you need.
The reason I'm asking is that Forms Authentication
seems to only protect ASPX pages and using this it could be used to force
people to log in who are trying to go directly to something other than an
ASPX page.
Having a hard time figuring this one out, but if I understand you correctly,
yes, it could.

Technically, what you need to do is set the appropriate Content-Type header,
ideally Content-Length as well, and write your binary content to the
response's output stream.

In real world applications, I'd rather use a dedicated HttpHandler for
delivering images and such, because you hardly want all the Page processing
overhead for these specialized "content providers".

Hi Kevin,

I did a search to see if people are already using this and they are...so
much for a novel idea, hey? Here is a link, it explains it better than I
did and now I don't have to re-invent the wheel. Thanks again! Ken.
