Significant image quality loss in Safari

Permalink
Hi,

I'm currently working on http://grafomantestsite.com/ (special project) . When you open a project it open's in an ajax lightbox.

The images in there show a significant quality loss when opened in the safari browser.
Best example is in the lightbox when you click on the animated gif, bottom image with text.

Any way to prevent this? What is causing this problem?

Thanks for the help.

Edit: added 2 screenshots, chrome and safari, for comparison.

Default JPEG/image compression is set at 80%. You'd be best off setting this at 100%.

If you don't have this file "/application/config/concrete5.php", create it. Then add this:

<?php
return array(
    'misc'             => array(
        'default_jpeg_image_compression' => 100
    ),
);


If it is existing, just add this INSIDE the array ("array("):

'misc'             => array(
        'default_jpeg_image_compression' => 100
    ),

I added this, it doesn't seem to change anything.

Clear the cache, images reside in cache. For newly uploaded files this change will take place immediately.

Cleared cache, reuploaded the image. Still the same. Do you see the same quality loss difference?

The images look bad on both my Windows Chrome and my iPad Safari. Are you sure you've uploaded a high quality picture to start with?

Perhaps others can take a look too.

I added some images, different quality and dimensions in the lightbox for the animated gif. It all looks very crappy in safari (in comparison to chrome, firefox and IE)

I think the reason this didn't work for future users is because the file should be called concrete.php, not concrete5.php.

It ended up being a problem with css and scaling in Safari. I forced the width of the images in the lightbox by adding the image block dimension. That seems to fix it.
