Hi,

i'm having a problem on this page : http://slworks-united.com/aquitaine-destination/evenements

I have several galleries on the page, but when I click on one image I have all the galleries that open in PrettyPhoto.
I had help here but so far nothing works : http://dreamthemedesign.com/u-design-support/discussion/9131/prettyphoto-with-just-the-current-gallery


I created posts with just image attachments, and I'm filling the gallery shortcode like this [gallery id="XXX"] and for another gallery [gallery id="YYY"] but it's still the same.
The persone there said that it's because of the code generated, which is rel="wp-prettyPhoto[gallery]
I'd like to know how I can have rel="wp-prettyPhoto[galleryXXX] and rel="wp-prettyPhoto[galleryYYY] when I specify an ID, and just rel="wp-prettyPhoto[gallery] when there is no ID specified. I tried to look at the code, but I can't manage to find where to make the changes.

I see that the HTML code retrieves the ID to create the class galleryid-XXX so I believe it might be possible to get the XXX and put it in rel="wp-prettyPhoto[gallery]

How to do that ? I'm desperate :(

And I'm not even sure if I made myself clear enough :/
