have slide show that loads many images either 1 or 2 at a time, would like to preload the "next" image set to speed it up, but any preloading "scripts" that I've found end up not using the cache and "double loading" the images anyway. You can check out the slide show at
http://24.223.138.102/art_232_chapter_14/art.htm

but you must use internet explorer for the page to function properly. Can you suggest any scripts? or techniques?

Any help is appreciated!
Jan

in case you were wondering, here's the script that runs the slide show (any suggestions? questions? etc?)

I honestly can't make head to tail of that page.

But in general, pre-caching an image in JavaScript is done by creating a new image object loaded with the image you want to preload like so:

myImage = new Image()
myImage.src = "url_to_image_file.jpg"

And you can check the boolean myImage.complete to see if it's loaded yet.

Although, with images that big you'll want to be checking conditions to see if the preloads are finished before preloading the next set because most dialup users will click through to the next page before those images have preloaded. If that happens before the preloads are done then they won't be cached properly and it'll restart the load.

All in all, is sounds like a lot of work for very little gain. Why not just compress the images well and have them load normally?

Furthermore, thumb nailed image links are a great bandwidth saving way for a user to navigate through a series of images. Personally, I'd much prefer a page of thumbnails to a linear step through that preloads the next set of images.

Basically what Dracusis said ^^^^^^^^^^^^^

We have an FAQ on the subject here:

:FAQ: How do I preload images with Javascript?

However, I really can't see much point to preloading images for this kind of thing - they are really just useful for things like mouseovers, etc. and you might be wasting more time than you save. Follow Dracusis' instructions and think about making the simple lefthand side of the image text.

Should explain the page....

It is intended to allow students to review a slideshow that is presented in a classroom environment. The slide show presents both text (as a jpg) and images either singly or in combination. I set it up so that users could click the text or image to see the image full size (a mouse over event presents various data about individual images). The advantage of NOT using a thumbnail is that the user can get a reasonably good idea of the subtle nature of the artists work (it's for an art appreciation/history class) "instantly", with a simple click allowing for an immediate "full size" view.

Since I see it from the computer that it is "broadcast" from the images load instantaneously, the only other computer I have to use remotely is on a T1 connection, so the loading of the images was fairly fast I hoped that preloading the "next" images would allow for a smoother transition from one "slide" to the next. Anyone access the page on a 56K? How slow was it?

If I had to guess the person who was sent to M$ was not using Internet Explorer (the scripts that I use have only been developed for IE thus far) Can Netscape resize an image on the page?

Hope this explains a bit....

Thanks for your help!

Jan_man ::: Not sure how well you know flash, but Flash MX comes with a nice slide show app. The slide show in questions loads slow for me. I think you'd be better off optimising your images. If they are to be lage file sizes, try a low src image as the main, while the larger file loads behind it.

Jan_man ::: I just had another idea. How about using a layer to load the images. Use the layer to hold the description of the images, use the onload feature in DW, while the user is reading the des. the image will be loading behind it, and when it's done, they will see the image. Just an idea.

Mob68,

I don't know what you mean by a Layer (I'm not too well informed about javascript/html). But if I can figure it out...

The other problem is that I have a program that writes the javascript -- I'd have to modify it as well! If there were more information for the user to read the layer sounds like the way to go, but the text as such is quite cursory...

Thanks!

Jan_man ::: I have used this option for two sites that needed a little longer to load the images using dial-up connections. Basicaly (and this is unique I think to DW), you build the page as normal (are there any normal pages anymore?) and when complete or not, you add a layer to it, making sure it spans 100% of the page horisontal and vertical. Chose a background color for the layer. Select the layer, and click on the "body" button on the bottom left hand corner of DW. Make sure you slect this. Then in the behaviors window select show/hide layers "onLoad" and you should be done. You can also use the leayer to add text to where you can inform people what's going on if they don't see the images right away. Keeps people on your page.

If you require IE anyway, check this place out for a preload that does basically what you need, unless I missunderstood you.

Preloading? I use the most basic and silly (and failproof) way... I just put the images I want preloaded on the bottom of the page, I add width=1 and heighth=1 to them all... easy as pie.

Amikeal,

That page seems to do a continuous preload of the images (it never stops the preload process); I think the javascript might have an error...

The script that I pointed to (the art.htm) has about 300 images -- you'd have to wait an awfully long time for all the images to preload before proceeding......
