Linking to lightbox on an album from a URL

That is not possible.
For lightbox to work, the following html for all the images to show needs to be present:
(prototype)

<a rel="{lightbox keyname}" href="{url for the lightbox image}" >
    <img src="{url of thumbnail image}" />
</a>

This means that the thumbnails or the sildeshow or any other wppa image type must be present on the page to activate lightbox.

You can use the wppa embedded lightbox for non-wppa images by ticking the box in Photo Albums -> Settings admin page Table IV-G5 ( and IV-G5.1 if you like ). You can open lightbox by clicking on the images.

Hi Jacob,
Based on your suggestion, I have done some experimenting, and the following seems to work.

My anchor with the thumbnail image of the first picture in the album is for example:

<a href="/ic-ivrea/wp-content/uploads/wppa/950.jpg?ver=3" rel="wppa[alw-1-31]">
<img src="/ic-ivrea/wp-content/uploads/wppa/thumbs/950.jpg" alt="" width="200" height="133" />
</a>

where wppa[alw-1-31] should be your lightbox keyname and …950.jpj are the URLs to the first picture in the album and to its thumbnail as found in Album Admin.
By the way what does [alw-1-34] stand for, (given that 34 is my album’s ID?)

I had to put the covers of the referenced albums in my page, but since I did not need to show them I placed them in a hidden division, as follows:

<div hidden="">
[wppa type="cover" album="31..34" size="auto"]Any comment[/wppa]</div>

Does that make sense or can I do better / more easily?
Thanks again,

Guido

If it works, it is ok to do so.

Let me explain rel="wppa[alw-1-34]

rel=”wppa” triggers wppa software to do the lightbox functionality.
rel=”{lightboxkeyname}[setname]” means: there is an array of items, named setname, to be treated as a set: to scroll through or to run a slidshow.

The setname in wppa: alw means: source is album cover ( i do not remember where the w stands for); 1 is the sequence order number of shortcodes or widgets on the page, starting at 1; 34 is the album id. So even when there are duplicate instances of album 34, there will be different sets; e.g. [alw-1-34] and [alw-2-34]
