Hai guys,

I am planning to do a Basic slide show. i have now 1000 images in my ftp folder with different different names.

Now i need to do a basic slide show which has buttons next, prevous, pause, resume etc.

Now i need to start the show using randam images selected between 1-1000 numbers.

so how to do that? is my below plan will work.

say, the slide interval is 5seconds, so i have plan to pick 1 image randamly on each interval. now say 55 selected, how to connet that number with the images in the ftp folder. since the images files have no key like thing?

You are going to need to use serverside code to read the folder and build an array of filenames.
You could then generate this into a javascript array into the page, but, a thousand element array definition would add a substantial overhead to the page.

A better option would be to have the code that reads the folder for filenames generate a javascript variable with the file count for maximum random number, then use a client side random number generator along with a AJAX remote call to get the filename for the next image.
If the images are quite large, using two synchronised intervals would be recommended, one to preload the next image to be shown (maybe at 2 seconds) and one at 5 seconds to switch to the preloaded image.

You could take this a step further and queue up the images in an array using push() and shift() to create a shift register (LILO) of preloaded images, though that would potentially start to eat into client resource pretty quickly.

ok christ,
excep ajx part i can undestand the other parts.
so the js with php will do the job right.

mmmh chrishirst is ryte. Afridy! follow his approach.
Create JavaScript array with Image path using the server side script, then randomly choose from the array.

Why you should not eat a piece of Ajax?

thank fireblade,
hm, i should also start learning ajax.
