Hi!
I just started using Zenphoto (v1.2.8) for its great SEO pages. Now I have a problem with the bundled Slideshow plugin (v1.2.7).
I have an album with about 50 images.
Steps to reproduce:
1. Using the "ordinary" Zenphoto gallery interface, navigate to any image that's not the first image, for example image #5, and start the slideshow.
2. Immediately press the back button in the slideshow.
Expected result: image #4 is shown
Actual result: a random image forward in the sequence is shown, such as image #9.
Then I can press back repeatedly until I reach the image i started from (#5). Now when I press back, I get to a larger-numbered image such as #25. If I press back again until I reach #5 and then press back again, I reach a even larger number, such as #42. If I wait long enough, the back button works normally, i.e. I get to image #4.
To me this behaviour indicates that the plugin starts to prepare the slideshow images from the starting image (#5) and forwards. When I click back, the "latest prepared image" is shown, and this will be an image with a larger number than the starting image until the preparation code has reached the last image (#50) and then finally prepared image #1 to #4.
Would it be possible to fix the plugin so the back button works immediately after starting the slideshow?
