You need to read the instructions for using JAlbum and/or the Porta slide
shows. In the case of Porta you will create the slide show files on your
local computer from a group of, or a folder of .jpg files. Porta will make
copies and organize those copies in various folders of thumbnail images,
midsize images, and perhaps full size images along with some javascript,
etc. All of those "web files or html files as I called them" are accessed by
a "home page" of sorts which is called "index.html". Once again read the
instructions for how to use Porta or which ever slideshow generator you use.
Once you produce your slideshow files you upload them (individual files and
folders) all to that subfolder you created on your host which I called
"Album". Your web page preview will not import the slide show until you have
uploaded those files. You can also preview the album on your local computer
by just double clicking the index.htm file just as you would preview any
..htm file.
As to the code fragment box placement and or size you will just have to
experiment. In my case I found that 700X600 code fragment box, centered on a
760 pixel wide box gave me the results I wanted based on the size of
thumbnails and other size images I chose. I have used both Porta and JAlbum
and in both cases the photo album adjusted to the iframe window I created,
gave me optional thumbnail sizes, midsize and full size images, plus
different skins.
Welcome to web design by trial and terror. I have given you the basic
framework and code snippet to use an iframe to import one of the slideshows
that you can produce with JAlbum, Porta and other slideshows. SPike gave you
a framework and an approach to use if you want to import a video. Now it is
up to you...have fun.
