Stop slideshow from starting over

**Ponder** · 05-24-2012, 12:20 AM

1) Script Title: Conveyor Belt slideshow

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...rightslide.htm

3) Describe problem: Working great. We have a link for each image. When clicking an image and going to that link, when you go back to the page with the slideshow, the slideshow starts again from the beginning slide.

Is there a way to have the slideshow start where is was when the image and link was clicked, and not start again from the beginning.?

Many thanks...Ponder

Hi vwphillips....Many thanks for responding......

I placed the code just where you show it to be but did not change it at all...and it did not do anything to restart the conveyor where it stopped.....

There was no change..

Should I be doing something with the code in addition to placing it where you show it??

Thanks for helping me....Ponder

He means for you to use the entire script from his post. He has made many modifications.

The red part is simply to indicate where you can configure the cookie's behavior.

The name (cookiename) can be any quoted string with no spaces containing only letters, numbers, dashes and underscores and must begin with a letter or underscore. It should be unique. Like if you have different conveyors on different pages, use a different name on each page. If you have the same conveyor on different pages and you want them all to remember where the others were, use the same name for all of them.

The days is the number (unquoted) of days that the cookie will persist for. The way the code is written, that has to be at least 1. Well it could be a decimal fraction. 1 is reasonable. A session only cookie might be more appropriate but that's not an option in the current code provided.
