Hi,

I’ve been reading over the documentation for a way to grab a random image from a Album, does anyone have a suggestion? Maybe I missed something.

Thanks!

That feature is not applicable at this time. You can file a Feature Request at http://github.com/splittingred/Gallery/issues/

Any update on this one? I tried

[[!Gallery? &album=`5` &limit=`1` &thumbWidth=`980` &thumbHeight=`153` &toPlaceholder=`AlbumImage` &thumbTpl=`ImageTpl` &albumCoverSort=`random` ]]
<div id="headline" style="background-image: url('[[+AlbumImage]]');">

</div>

If I call GalerAlbums, I can’t choose the single album, right?

Update and solution:

I found non documented code which indicated that random can be used:

if (strcasecmp($sort,'rand')==0) {
    $c->sortby('RAND()',$dir);
} else {
    $c->sortby($sortAlias.'.'.$sort,$dir);
}

So here is my chunk [[$headline]] which puts a random image from a predefined album (5) behind a div box:

[[!Gallery? &album=`5` &limit=`1` &thumbWidth=`980` &thumbHeight=`153` &sort=`rand` &toPlaceholder=`AlbumImage` &thumbTpl=`ImageTpl` ]]
<div id="headline" style="background-image: url('[[+AlbumImage]]');">

</div>

[[$ImageTpl]] is simply:

[[+thumbnail]]

which puts out the path to the image in the size of &thumbWidth and &thumbHeight.

Looks like this: http://bergischer-ring.bytethinker.com/galerie.html

Cheers,

sort and dir are both documented and I don’t know how they relate to the albumCoverSort. I would experiment all of these options it may be that there is some clarification to be made in the docs.

http://rtfm.modx.com/display/ADDON/Gallery.Gallery - no "rand" mentioned, no answer given here in this thread.

albumCoverSort was the only documented way to randomize the choice of an image. It uses "random" instead of "rand". So I didnt even hit it by trying.

for this kind of galleries, with only view images for each resource, there is the MIGX-TV as an alternative way.
There is a randomize-property for the included getImageList-snippet.

you can buy me a beer, if you like MIGX

-.-
maybe I need to use this snippet of yours as my "header image gallery" destroys my content galleries.
And: the header images are beeing taken from the current content gallery, not from "5" as I defined.
