Hi,

strange...try this:
open "download.php" and replace:

Code: [Select]

@readfile($file_path);

with:

Code: [Select]

ob_implicit_flush(0);
$fp = fopen($file_path, "rb");
fpassthru($fp);

Hi Jan,

Thanks for your quick reply  

I tried it but it doesn't work  

but i realized when i comment out the lines

      header("Content-type: application/octet-stream");
      header("Content-length: $file_size");
      header("Content-Disposition: attachment; filename=\"$file\"");

and click on the download button, it brings me to the image instead of a popup download box.

I also thought it could be due to IE but I tried with opera browser and its the same thing....

any ideas?

thanks!

Do you use only images stored on your server or also images linked from other servers?

Jan

[m00mo0]

The images are located on one server only.

When I uploaded the image and thumbnail I only have to fill in either the upload file location or the url right?

 :

[Jan]

Yes, thats right. But i want to know, if all images are stored on the same server as 4images is installed, or do you use somtimes the URL field?

Jan

[m00mo0]

Yup,

the images are stored in the same server as 4images

[Jan]

Ok, replace in download.php

Code: [Select]

ob_start();
@readfile($file_path);
$file_data = ob_get_contents();
ob_end_clean();
$file_size = strlen($file_data);

with:

Code: [Select]

$file_size = filesize($file_path);
$file_data = fread(fopen($file_path, "r"), $file_size);

Hi Jan,

Thanks alot for all your help. It works now but I think the problem was with using URL instead of using the upload feature.

After amending download.php, I could get the download popup box but the images filesize = 0 bytes, so an empty file gets downloaded.

But if I use the upload file instead of specifying URL, the download works.

Thanks!

I too see the download zip button disappearing.  My details and lightbox templates both contain {download_button} and {download_zip_button}

1.  In the details.php view, if there is no user logged in, I see the download_zip_off.gif button.  If I log in, the button isn't replaced by download_zip.gif, it just disappears entirely.

2.  The lightbox.php view doesn't display the download_off.gif button.  Obviously I can't view a lightbox if there is no user logged in.

Additional info:

I have 4 images referenced by URLs and 1 that was uploaded.  All images reside on the same server where 4images is installed.  All are in the master domain, which is to say that there is no subdomain involved.  The details.php view was for the uploaded file.  The lightbox contained only the 1 image that was uploaded.  

Any ideas?

To use the "download as zip" feature you need the module zlib installed on your server. You can check this with phpinfo().

2.  The lightbox.php view doesn't display the download_off.gif button.  Obviously I can't view a lightbox if there is no user logged in.

Thats right, only logged in users can use the lightbox.

I figured it was missing a module.  At the time, I didn't even think it might be zlib but now it seems obvious.  Thanks.  I've asked my web host to install it for me.

How do you use phpinfo()?  I looked at page_footer.php but wasn't able to figure out how to trigger the if-statement.

[Jan]

Simply create a php file with this code

Code: [Select]

<?php
phpinfo&#40;&#41;;
?>

this will show you all coniguration informations about your installed php version.

My server's phpinfo():
(edit - removed, url no longer valid)

zlib appears to be installed:
[Chris@webspace1 dev]$ rpm -qa | grep zlib
zlib-1.1.3-25.7
zlib-devel-1.1.3-25.7

The 4Images admin control panel has "Use GZip compression" enabled.  PHP safe mode is off and still I do not get a "Download As Zip" button.  

Is there some add-on PHP module required?  Any other ideas???

hi,

Code: [Select]


'./configure' '--with-apache=../apache_1.3.23' '--with-config-file-path=/etc' '--with-mysql=/usr/local/mysql' '--with-gd' '--enable-ftp' '--with-xml'


your PHP ist NOT compiled with zlib.
