I already started a similar Thread under [Forum, topic 27004] Support for animated GIFs.

AFAIK a change in some core places would be required. Not sure if and how this could be done via an extension - my piwigo skills would only suffice for a "hack" in my local installation. Still on my todo list, but no progress so far.

If you're still interested in this you might have a look at my update in http://piwigo.org/forum/viewtopic.php?id=27004.

I have managed to get it working by changing only one core file. But that surely needs some more testing to see if I have thought of everything. Also, my instance of PHP uses the external imagemagick library, so I could only do & test the change for this configuration.

Hi Rolf,

let me try to answer as best as I can:

1. Do I only need to copy your version of image.class.php to overwrite the original file in piwigo\admin\include ?

-> Yes, but you should make a copy of the original file before :-)


2. How do I install ImageMagick on my website: I use a WIMP platform: Windows 10 pro, IIS 10 webserver, MySql, PHP.

-> Luckily, it was pre-installed by my hoster. A quick google search revealed various matches, e.g. http://herbmiller.me/2016/06/16/install … ick-php-7/

3. Or is ImageMagick already pre-installed in Piwigo 2.8.6. (ploader plugin?)? The Piwigo environment says: GD bundled (2.1.0 compatible).

-> In that case you don't have ImageMagick installed (neither as stand-alone nor as PHP-Module). For that page to show Piwigo checks what is installed on your server. So if you manage to install ImageMagick properly, it should show up, e.g. like "Graphics Library: External ImageMagick 6.8.9-9" (my case)

4. Do I need to make separate thumbnails (animated or not), or does Piwigo take care of file-sizing etc. during uploading of animated-GIFs?

-> Piwigo creates files "as required" - normally when you request the file its checked whether the format is already cached (under the data/_i folder). If not, the conversion is started. For GIFs I have found that this takes a long time and should be triggered directly after the upload. This can be done under

Photos->Recent photos, Select Photo, Select Action "Generate Multiple Size Images"

Thomas

Hi Rolf,

pictures or artwork shouldn't make much of a difference to ImageMagick :-)

a) No thumbnail of animated GIF file is displayed on level of album/subalbum.
-> Works on my end: http://www.feuster.com/piwigo/index?/ca … tartcat-12

b) Many upload problems with animated GIF files.
-> Such as? Any errors & logs, ...? Maybe timeouts due to size?

c) Large animated GIF files are not shown, such as:
FapTrailer8-animationToFro2-RGES.gif (e.g. 1060x1060 px, 922 MB, 255 colours).
-> Could you mail me on of those GIFs? Then I could try on my end and maybe see, where its breaking...
-> If you have organized by galleries you could check under piwigo\_data\i\galleries\galleryname if there are re-sized versions of your GIF (endings like -la, -me, ...) and if they are still animated
-> Does re-creating under Photos->Recent photos, Select Photo, Select Action "Generate Multiple Size Images" complete without errors?

HTH,
Thomas

Hello Thomas,

I have been trying to generate multiple sizes the way you suggested. I only get the red remark that none has succeeded.
Furthermore, Ik get duplicate subalbums, for example in the album BeaytyMotives, I now have 2 subalbums called Animations. I found a way to delete the images in the second Animation subalbum, though Piwigo shows the error message:
http://www.rolfsnijders.net/admin.php?page=photo-314
--------
Warning: [mysql error 1064] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 3

Fatal error: Call to a member function fetch_assoc() on boolean in I:\Web\Site\piwigo\include\dblayer\functions_mysqli.inc.php on line 226
---------
The image concerned has disappeared from that subalbum, but now I can not find a way to delete the duplicate (empty) Animations subalbum (within BeautyMotives).

I do not know if is it is feasible to copy the original files in the Piwigo subfolder piwigo\galleries\BeautyMotives\Animations, and then synchronize the complete site or the other way around. In which order should I maintain data? Is the following correct:
1. First on the local/Windows level of files?
2. Then online (via the website URL):
a) first: Tools | Maintenance: repair optimise database, then
b) second: Tools |  Synchronise directories + files ?

Friendly regards,
Rolf
