Has anyone created a plugin for a before and after gallery? I cant seem to figure out how to accomplish this.

I presume you mean a gallery where each "before" image has a parallel "after" image. I don't think it's been done with zenphoto, but assuming you're willing to use some kind of album/image naming convention it shouldn't be too hard to put such a theme together. Perhaps have a parallel albumname_before album where each image has the same filename as its "after" image. Then iff the "before" image exists, the image page should show two images (the default one and the one with _before added to the album name), possibly switching/hiding one through the magic of css. Then hide/don't publish the "before" albums and you're pretty much done.

I'm sure putting the before and after files in the same album could be done but it would be more work because you'd need to get the album page to skip the before images.

Of course, if you mean something different, I don't know.

Codeface: Could you please specify a little further what you are asking about?

I suppose you could use some CSS or Javascript on your image page....
If your after picture is after1.jpg, code the hover to load before1.jpg

i have something like this. just subsequent your images as (imagefilename)1.jpg and (imagefilename)2.jpg unless you want some sort of hover over and image change effect which can be done mootools probably.

Hi everyone. I meant exactly what jlang mentioned. two pictures side by side. I'll try the naming convention. I guess I then modify the image.php page?

How would I create two thumbnails for the album? For example, when they enter the album they should see two small thumbnails. A before and an after. When they click on any of the two it should link them to the page that shows both.

I basically need to copy this functionality

Notice the links are in rows not images as in zenphoto. If zenphoto could add this it would be GREAT! imagine the possibilities. Construction, design, makeup, cosmetic dentistry, cosmetic surgery, auto, ...

Now finally I got what you want...:-) If the number of images allows, you could do that probably with subalbums without hacking too much.
