Best way to dynamically load jpegs?

[Marcus]

I am new to Flash and actionscript and just getting my feet wet
learning how to put the pieces together. I would like to dynamically
load series of jpegs and loop through them at, say, 1 every half
second. When the last one is shown, then it should go back to the
beginning and continue. I tried the following:

- created a blank movie clip on a layer and called it "imageHolder_mc"
- created a function called loadImage() that loads the jpeg by calling
the loadMovie flash function, giving it the name of imageHolder_mc for
the the location of where to load the jpeg into.
- called the setInterval flash function like this:
setInterval(loadMovie,1000)
so a loadMovie function will be called every second and thus the new
image will be loaded.

The result is that the jpegs do load and loop, but as my function is
always loading the images from the disk, there is a slight delay
between images loading which causes it to flash unacceptably. How
could I load the images only once and have a smooth transition from
one to the other? Can I create a time line with one movie clip per
frame, and call the loadMovie function on each of the frames?

Any suggestions appreciated.

Thanks,
Marcus

does Flash MX glitch when you load an image dynamically ?

I have Flash 5 and I've been thinking of upgrading... all my dynamic image
loading is done on server scripts: it's fast and reliable.

What I would do (or what I have done) is to load each image to seperate
movieclips, and after loading start the slide show. You're asking buch
of questions here and it would take a lot to tell all the details.
However, how it works in theory is that all the movieclips are in same
coordinates, and only the one on the top is visible (using the _visible
-property of movieclip). When displaying second image, I set _visible of
second image to true and current image to _false. This I would loop,
always swapping to the next image in row and when reached to last image,
swap it with first image and so on. Transitions could be built for
example fading the alpha of previous image to 0%, or using another
movieclip as mask for nice animations. I'm sorry for not supplying
actual code, but I have developed it as a part of commercial product. I
can however give some guidance and main ideas, but I suggest you to work
on this base or finding free working slideshows from the web.
