random rss feed

Hello Masters,

Do you know if the piwigo 2.8.2 have any option to make a rss feed with a random image ??

I had this function in my old gallery3
http://fotos.vhsantos.net/rss/feed/rss_ … m/portrait
and here the original code
http://codex.galleryproject.org/Gallery … rss_extra.

I used this to put a random photos on distinct social networks with a https://dlvr.it

any suggestions ?

thanks and attentive.

Re: random rss feed

Hello,

I was "working" in this request and attached is the patch.

Sorry, for the code...Im not a developer, I just copy and paste code from one place to other, but I think that is OK.. maybe a good developer can look and improve it.

to access the random feed:
http://site/feed.php?random

thanks and attentive.
