RE: Passing paramters between windows

Hi

You can do this three ways (well probabli more but these are the first
that come to mind).

1. Just simply set a variable in the parent (source) window and retrieve
it in the child window (photo window).
	In Parents:
		MyVariable = "something";
	In Child:
		Image = parent.MyVariable;

2. Tag the variables on the end of the URL string as parameters like so:
	http://www.domain.com/page.html?MyVariable=Something
You can then use JavaScript to retrieve the values from the URL. You can
find instructions on this at http://imptech.net.

3. If you got access to a server side language such as ASP then you can
do the same thing as number two but instead of using JavaScript, use the
ASP to retrieve the values which is a lot easier. For example in ASP all
you do is:
	MyVariable = request.querystring("MyVariable")

If you need more help let me know.

Subject: Passing paramters between windows

Having spent hours trawling through books and help sites, i'm about to
give
up - i hope someone here can help, and forgive me asking this.

I want to pass, and use, a value to an exiting  window.
I can open a new window, and i can open an exisiting window and pass
some
information in - but then i lose the style and content of the window
(that
is already there) -  although the address is the same as my original
window,
i've lost what was there before i started.
I've seen ways to pass values to a target window and ways to grab values
from the source window (using a form) - but i cannot figure out how to
do
what i want.

Which is:

My site has a number of thumbnail images, on various different pages.
When clicked on, i don;t want to just open up a new window to give the
full-size photo;
I want to open up my existing "SinglePhoto.htm"  window (which already
has
my style, logo, structure defined) -
and add a new title (that is a parameter from my source window) , and
insert
a named image  (that is also parameter from my source window).

i.e. I have a single-photo page with a template, which i want to use
every
time my viewer opts to see a full-size image;
and into this template, I want to embed a named "image/myPhoto.jpg", and
give it a title and/or heading, also defined in the source window.

I've found lots of pieces to this jigsaw (but i'm not sure they're all
from
the same picture) - but i cannot put them all together.

Many thanks for any help!
