I am using piwigo 2.4.1 but I have a little problem. I uploaded different similar pictures (same size, same day,...) but some are visible in preveiw and others you can't see the picture.
What's strange too is that when I save on my computer a picture where we can't see the preview, it is saved well and than I can open properly the picture whith a software on my computer (for ex galery photos windows).
Is it a bug?
I tried a lot of things: reduce the size, change the name, put in another folder on my website, tried to upload again, ... but nothing helped.
The gallery is private (the people on the pictures don't want the gallery public) so I can't show you the problem in real time. But I found something extra. When I try to open the link on the website itself I have got this error:
Call to undefined method Imagick::setImageOrientation()
And now I see that its all the pictures who has been rotated that aren't visible. But I have no idea how I have to fix this problem.
1) Activate plugin LocalFiles Editor
2) on screen [Administration > Plugins > LocalFiles Editor > local config] add:
$conf['graphics_library'] = 'ext_imagick';
