Hi Tommi,
I have been trying the above, and I don't understand how this is
supposed to work, and it isn't in my case.
I wrote the following html where the "arg1" input parameter is simply an
image number in a list of images, so I can get different image results.
Primitive, but that's fine in this case, and it works.
<html>
<head>
<title>Tntnet-application hello</title>
</head>
<body bgcolor="black" text="White" link="yellow" Vlink="yellow">
<h1>hello</h1>
<p>Hello Tntnet world!</p>
<table>
<tr> <td> <form> <input type="text" name="arg1" value="
<$arg1$>"> </form> </td> </tr>
<tr> <td> <img src="/theimage.jpg"> </td> </tr>
</table>
</body>
</html>
Once I get the image number I generate the image data and do the
following as you explained before:
reply.setContentType("image/jpeg");
reply.out() << image_data;
The result is that the image fills the whole browser window, everything
else is gone. Somehow, the image data is supposed be placed where the
img-tag is, like you explained. But it isn't in this case, and what if
there were several img-tags in the page? Where is the image supposed to
go then?
Somehow there must be a match between the name of the image in html and
the "name" of the data returned, but the exact technique eludes me.
Could you perhaps point me to where this is explained?
Best regards
Carsten Arnholm
