is there anything like NeoDownloader for ubuntu to download all the images from a link ....or can it possible to download directory from webserver containing photos?
If you use Firefox then get the Download helper add-on. It is a good Firefox add-on DownThemAll. It can list and download all of a certain file type, and it have some advanced settings.
DownThemAll lets you download all the links or images contained in a webpage and much more: you can refine your downloads by fully customizable criteria to get only what you really want.
Give it a go, I hope it does the trick.
