Open jQuery prettyPhoto API to an image other than the first one

prettyPhoto is neat little jQuery plugin, that makes it easy to do lightbox style image (or “videos, flash, YouTube, iframes and ajax”) overlays on your page.

Let’s say I have 5 images that I want to popup and order is important, but sometimes I want to start showing the third image. I can use their API to open a prettyPhoto popup.

$['1.jpg', '2.jpg', '3.jpg', '4.jpg', '5.jpg']);

But that doesn’t open with the 3rd image displaying? I could reorder the array like this:

$[ '3.jpg', '1.jpg', '2.jpg','4.jpg', '5.jpg']);

Sometimes order is important, though. So I want still want the images in order but I just want 3 to be the one that starts large.

Here is all of the documentation you get about using the API.

The public API functions are the following


You can also open galleries using the API, just pass arrays to the open function.

api_images =['images/fullscreen/image1.jpg','images/fullscreen/image2.jpg','images/fullscreen/image3.jpg'];
api_titles = ['Title 1','Title 2','Title 3'];
api_descriptions = ['Description 1','Description 2','Description 3']

Digging into the jquery.prettyPhoto.js source code you can see exactly what is going on in the changePage method.

$.prettyPhoto.changePage = function (direction) {
currentGalleryPage = 0;
if (direction == 'previous') {
if (set_position < 0) set_position = $(pp_images).size() - 1; } else if (direction == 'next') { set_position++; if (set_position > $(pp_images).size() - 1) set_position = 0;
} else {
set_position = direction;
rel_index = set_position;
if (!doresize) doresize = true;
if (settings.allow_expand) {
_hideContent(function () {

Basically, the method is using magic string matching on ‘previous’ and ‘next’ to do a +1 or -1 on the set_position. If the parameter sent in isn’t ‘previous’ or ‘next’ it sets set_position equal to the parameter sent in.

That is great news! Now, since I know the index of the image I want to show I can just call changePage with that value as the parameter, like this:

$['1.jpg', '2.jpg', '3.jpg', '4.jpg', '5.jpg']);
