Title: Resize images on details page
Post by: conflagration on October 13, 2009, 01:38:35 PM

Hi community,

I just installed 4images and I really like the simplicity of the installation and configuration, but there's still one problem left: I want to use 4images to upload high quality photos, so I allow picture sizes up 10k x 10k pixels. Although I want people to be able to download the pictures in this high resolution, I want the pictures to be shown on the details page resized to a maximum with of 1000px. Is there a way to do this?

Thanks in advance,
Thomas

Hi bergblume,

thank you for your help. I took a look at the threat, and the solution there could be a compromise. But i would prefer something, that would do a server side resizing to avoid unnessecary traffic. I just want the "download" button to return the full size image.

Best regards,
Thomas

... you are right ... sorry ... I've corrected the link ...
... but remember ... with the resizing MOD you are loosing the exif-infos from your images ...
... but there are still other ways to show the exif-infos on the detail-page ...

Oops, is it ? Can you please kindly point me out, how to show exif-infos into the page for those resize images ? Because I really need exif-info and resize mods that's why. Thanks mawenzi.

With Regards,

... the loosing of the exif-infos is not a 4images problem ... it's caused by using of the modul "GB Bibliothek" for resizing ...
... here some solutions to show exif-infos on detail-page by using resizing MOD during the image upload via browser / website-uploadform ...

1. by storing of the exif-infos during the upload process ...
    [MOD] EXIF V.1.7.6 Suchfelder Erweiterung : http://www.4homepages.de/forum/index.php?topic=21053.0 ...

2. by using of the big-folder solution ( storing of the original image in the big-folder ) and reading of the exif-datas from the "big"-image ...
    [TUT] One Image - Three Sizes : http://www.4homepages.de/forum/index.php?topic=20496.0 ...
    and then is to change the path to the big-images in the "exif function" in includes/functions.php ...

PS. I use solution No. 2 ... ;)

... in includes/functions.php ( e.g. vers. 1.7.7 ) find in section "function get_media_code" ...

if ($detailed_view && $image_info[2] == 2 && function_exists('exif_read_data') && $exif_data = @exif_read_data($src, 'EXIF')) {


... and replace it for your new big-image path with the following ...

$src_big = $site_sess->url(ROOT_PATH."data/media/".$cat_id."/big/".$media_file_name);
$src_exif = (!file_exists($src_big)) ? $src : $src_big;
if ($detailed_view && $image_info[2] == 2 && function_exists('exif_read_data') && $exif_data = @exif_read_data($src_exif , 'EXIF')) {


PS. : or use it similar, the part "EXIF" varies in the different 4images versions ... !
