||SeqDownload v1.26 - Automatically download images from the Web
Copyright (c) 2003 - 2010 Nir Sofer
Many Web sites provides "live" images that are automatically updated every few seconds or minutes.
When you browse to a Web page with live image, you always get the latest image from the last few minutes.
But what about viewing some historical images from a few days ago, or watching the animation of the images from the last few hours ??
Some Web sites provides limited options to do that, but most Web sites only allows you to watch the latest image.
This utility allows you to automatically download an image file in every few seconds or minutes
(according to your selection), and save it to your local drive.
After collecting a fair amount of downloaded images in your local drive, you can easily
create beautiful animation from the downloaded images or simply watch the historical images on your local download folder.
You can also use this utility to frequently download non-image files, and store
them on your local drive, so we'll always have in your computer the latest file from the
remote Web site.

the configuration of the download item, even while it's active.

a new sub folder folder will be create every day by using the date format you type.

specify, and overwrites the previous download. If you select this option, you won't be
able to create animation, because only the last download is stored on your local drive.

which increases by one in each download.
The "Leading Zeros" field determines the minimum number of digits in the counter.

the current counter value is 5, the final filename will be "MyFile005.gif"

yyyy for 4-digit year
hh for hour of day (00 - 23)
nn for minutes in hour (00 - 59)

Netscape, and Opera. However, if you want to run the animation on older browser,
you should uncheck the 'Allow to pack all animation files in mht file' option.
Packing animation into one file
Internet Explorer allows you to pack the entire Web page into single mht file, including the files and images in it.
You can also apply this feature on the animation page created by SeqDownload as long as the
'Allow to pack all animation files in mht file' option is checked.
The mht file created in this way contains all images need for the animation.
Using HTML Template (For advanced users)
When you choose to create Javascipt animation, SeqDownload uses the default html template to create the animation page.
Starting from version 1.10, you can modify the default HTML template in order to customize the animation page that SeqDownload utility creates.
If you want to create the animation from your own HTML template, follow the instructions below:
- Load template.html into a text/html editor.
- Modify the file according to your needs.
You can change/add style sheetes, add background image, add more images/text to the page, and so on.
After you make the desired changes, save them into a new filename.
- In the animation dialog-box, check the "HTML Template" option, and select the html filename that you saved earlier.
- When you click the "Create Animation" button, SeqDownload uses your HTML file to create the animation page.
The "<!--***NIRSOFT_CODE***-->" string is replaces by additional code needed for loading the images.

of SeqDownload. By using this option, you can start SeqDownload with another
downloads list (instead of using the default file). If you sepcify a downloads filename
that doesn't exist, it'll be automatically created for you.
