Speeding up java script loading

[Rich]

I inserted a java scritp program on a web page. It shows
a series of photos. It takes forever to load before
starting, even on broadband. Any way to speed up the
loading?

Thanks,
Rich

Does it have a preload image routine where it waits until all images are loaded before it
displays the first one??

If so, remove the preload routine and have the script go straight to the first image.

Hi Rich,

I'm guessing the script preloads all the images? In which case you'd need
to either optimise the images to get their file size down or load them as
needed - here's an example of 1 way to do this

That is JAVA applet code - not JavaScript
- JAVA has no preload
- JAVA may not be available to many users

In addition, a Java Applet does not consist of the tags in the page any more
than an image consists of the image tags in the page. The tags which were
pasted into anonymous's message are simply instructions regarding the
location of the Java class files (which may be large in size, I can't say as
I have never seen them), and the parameters to use on the client side. So
now, in addition to downloading all those images, the browser must download
the class file(s) for the applet.

Have you resized the images you're using to the actual size displayed by the applet, which is:
width=131 height=115

If you haven't and your using 600 by 800 or larger images it will take forever for the images to
download.

Check the actual size and the file size for the images and if they're bigger than needed, Resample /
Resize them with an image editor such as the free IrfanView.

BTW, you CAN pre-load images using JavaScript (much faster than using a Java
Applet). Just Google for scripts.
