Aresponse.Contents.Add('<td bgcolor=#FFFFFF align=left><img
src=bgblue.jpg></td></table></Body></html>');
Handled := true;

The above code chunk is a part of a program.

My question is:

Why PICTURES are not skown?

Any text is.

My guess: the img tag is not closed anywhere. Add '/' to its end.

Here comes the HTML code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-
equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<center><table border=1 width=720px><tr><td bgcolor=#FFFFFF
align=left>Where is my PICTURE?</td>
<tr>
<td bgcolor=#FFFFFF align=left><img src="bgblue.jpg" alt="kkk"
width=200px height=200px /></td></table>

IF I load it in the browser it works perfectly.

IF I run with FASTCGI with Aresponse.contents.LoadFromFile('aaa.html')
it WON'T display the picture!!!!

I do NOT see any problem with the little HTML code displayed.

The problem is somewhere else. WHERE? 

Best Regards

Put the image file name in double quotation marks?

In case of image, the problem might be the content type. You have to
set the right one. It's 'image/jpeg' for jpeg files. You can see in
your browser's developer tools to prove my guess (the default content
type is application/octet-stream).

----------------------------------------------------------------------
GiovanniF · 2013-10-23 11:14

I tried that too.

Doesn't work.

Thanks.

My guess is that the FCGI application is NOT sending the binary data
(picture) but
only the text .

Thanks.Give me the output of your browser's developer tools (something
like in the attached picture). I'm guessing your app doesn't even
serve the image correctly.

Which browser are you using?

Which "tool" are you talking about?

Thanks for you effort!

QuoteWhich browser are you using?Google Chrome, but recent Firefox
also has it by default AFAIK. You can also install Firebug on previous
Firefox.
QuoteWhich "tool" are you talking about?In Google Chrome:
Tools->Developer Tools (or Ctrl+Shift+I).

ok.

HERE WE GO 


See the attachment.

Now that's weird. You have /lamm/act2 serving image/jpeg while above
you specify a html file. If you use above code, there should be 2
requests. 1 for the html file, 1 for the image link contained in the
html file.

----------------------------------------------------------------------
GiovanniF · 2013-10-27 08:05

Try this:

Create a FGCI or a WebModule.

Then within the Module or FCGI try to load a HTML file
that contain
<html>
   <body>
      <img src="yourpicture.jpg">
   </body>
</html>

You'll see!

I believe that it is a bug, but since this components are not
documented, I'll look in the code.

QuoteI believe that it is a bug, but since this components are not

used it and it works just fine (for a long time). The problem is your
img requests blablabla.jpg, which sends /blablabla.jpg to the server.
If you don't have handler for this (either in your FCGI app or web
server), it won't work. Try the attached project (put yourpicture.jpg
in the same directory as the fcgi binary).

I thank you very much for the effort and the patient but THAT is not
the solution I am looking for!

I have to be able to load HTML pages with BOTH text and pictures!

Do you think that it kan be done  by HTMLpageProducer within fpWeb?

QuoteI have to be able to load HTML pages with BOTH text and
pictures!Well, it can. What do you think the HTML is? HTML is just
text. And again, if you see in the developer tools, you'll get TWO
requests. One is text/html, the other is image/jpeg. I guess you need
to learn about network and web programming theory more.
QuoteDo you think that it kan be done  by HTMLpageProducer within
fpWeb?Sure, it's just a (relatively) convenient way to produce HTML
pages.

Is there ANY example where I can see how to use  HTMLpageProducer?

BTW I have solved my problem 

I want to thank you a lot for all help!
