Re: Loading Images from PHP broken on Redhat Enterprise

[Kevin Smith <kevin@xxxxxxxxxxxxxxx>]

Hi Curt,

In that case, what on earth is going on.  This is the script which is on both servers:  However, I noticed that if I moved the following lines to the top of the script:

header("Content-Type: image/jpeg");
header("Content-Transfer-Encoding: binary");

..and hard-code the mime type, it outputs the correct headers, apart from "Transfer-Encoding:chunked".  Which seems to still screw it up.  The content length is wrong (13198), it should be 13184.  Looking at the RAW output of the image data, there is a difference.  I noticed 3381 was output as part of the image data, yet this is not so on the Server #1, that works.  Even if I fix the content-length header to what it should be, it still has some differences.

It still bugs me that the data is absolutely fine in the database, as I can save the data out of it into a file and view that file as an image with no problems at all.

Anything else you can think of?

Thanks,

Kevin

HI Robert,

Server #1 (working)
http://www.limiteds.com/includes/image_load.php?image_id=8522&field_id=image_full_2

Headers for this one:
Content-Transfer-Encoding: binary
Vary: Accept-Encoding,User-Agent
Content-Encoding: gzip
P3P: CP="NOI DSP COR NID CUR OUR NOR"
Content-Length: 12547
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive
Content-Type: image/jpeg

Server #2 (sad and not working)
http://www.limitedshop.co.uk/includes/image_load.php?image_id=8522&field_id=image_full_2

 
And This one:
P3P: CP="NOI DSP COR NID CUR OUR NOR"
Keep-Alive: timeout=15, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/html; charset=ISO-8859-1


Something is different.

Curt.
