Webcam - need a solution

[MZ]

Hello,
I have a webcam connected to the Internet.
I can access the current static picture of the camera using an url link. It
shows the picture with high resolution 1600x1200.

I would like to have a batch program which will do what follows every some
amount of time:
1. save the picture automatically on my local computer (which will be always
running)
2. lower the resolution of the saved picture
3. store it on the FTP in a particular folder.

Is it possible at all?

Surely that is possible, but Clientside JavaScript is a poor choice as
language for such a task.
Try a serverside solution, eg PHP, Perl, Java, Python, etc.
(Well, you can even use JavaScript as serverside language.)
Serverside makes things a lot easier for you: eg having libs at hand
that resample the picture.

It is certainly possible, but an ECMAScript implementation would not be my
first choice of language for doing it.

Javascript on the serverside means I can do it on the webpage? Would be
great!
Could you point me out some functions in javascript so I can get the idea
how to do it?

Thanks in advance

Hi,

I am not sure we understand each other.
I advised you to use a serverside language for the task (which COULD be
JavaScript, but this is really rare. PHP makes much more sense and
hosting is easy found.)

What you mean by using it on the webpage is not clear to me.
EVERYTHING on your webpage comes from a server (unless you are browsing
local files).

Could you point me out some functions in javascript so I can get the idea
how to do it?

I wouldn't advise you to use Javascript for this task.
You must learn a serverside language.

Hope this is clearer now. ;-)

Yes, it is clear now.
I don't like PHP so I was googling for a solution in javascript.
I would like to have a script which will dynamically create the gallery html
file when the file is opened.
And I have found a prety simple solution.
Please take a look at

http://www.softpedia.com/get/Internet/Other-Internet-Related/Javascript-Gallery.shtml

JavaScript gallery by Consoriana.
It enumerates the small thumbnail files put it into a table with hyperlinks
to the bigger files and gives you a nice gallery preview with next/previous
in each folder.
This is more or less what I am looking for and it works great!

However I need to modify it a bit.
Can you advise me what to change so I do not need to be dependent of the
file names?
I would like to store a different filenames in folders and I would like to
make it as universal as I can.

I think if we figure out a solution it can be usefull not only for me.
So any help apreciated!

You did not made a reasonable design decision. While there is no
"javascript " to begin with, chances are much greater that server-side PHP is
supported than that client-side JS and the host-provided interfaces it
relies on is. And ECMAScript implementations like JavaScript or JScript can
also be used server-side. (PHP can also be used client-side, but chances
are low that it is supported in a HTML UA.)

I would like to have a script which will dynamically create the gallery html
file when the file is opened.

Server-side PHP can accomplish this.

And I have found a prety simple solution.

But of course not a good one.

Especially "No scripting language needed such as PHP and ASP" is hilarious.
What do they think JS are anyway? Markup languages?

You are in no position to assess the quality of this code. However, in this
case neither am I, because all attempts to download it result in a broken
ZIP archive that contains only images and no script files. (And no, I did
not use a download manager and I tried both download locations.)

However I need to modify it a bit.

You do not expect anyone knowledgeable here to wade through this code in
their free time for free, even if it was possible, do you? RTFM or ask the
author instead; or get a minimum clue, stop using it, and start using better
code (maybe your own).

I would like to store a different filenames in folders and I would like to
make it as universal as I can.

Good luck.

I think if we figure out a solution it can be usefull not only for me.

You mean there is anyone knowledgeable here appreciating this supposed
reinvention of Wheel 0.7.5 (unstable), given the available alternatives?

Finally, the download worked. A strange thing, though. However, my
suspicions about this script have been confirmed. It is junk, for several
reasons, the least of which are undeclared variables all over the place.
