Most of the sites which host picture galleries usually have a sequential list where they sort in numerical order.If you are up to the task of downloading these long list of pics then it sure is a tedious job.I'll explain an alternative to this.Using this technique you will be able to download huge pile of images in a single batch.You will need Firefox for this and need to install an addon Down Them All.This addon is also a download accelerator and hence a multi utility tool.
1.Install Down Them All.
2.Go to the image gallery.Open The first image and final image in new tabs.
3.Right click both images and click on view image to get the image address.
For example http://******.com/movie/photogallery/images/abl-0001.jpg and http://******.com/movie/photogallery/images/abl-0021.jpg be the first and final images.Copy the link to the first image.
4.Go to Tools>Down them all>Manager
5.Add the url of the 1st image and at the end of the images you need to add brackets and the number representing final image.I will explain that in this example.
http://******.com/movie/photogallery/images/abl-0001.jpg is our first image and as we know the gallery ends at image 21.
To batch Download
Add url as;
6.Choose the directory to save files in and click ok.
Hope this information helped you.
