I am downloading pics from Imdb a lot (for work purposes). Without Downthemall! in FF or Opera, where you can download them with right click, i could not downloaded them with K-Meleon. Now, I finally found a way:
right click on the page, go to page properties --> pictures and download them with right click.

Please, next version of K-Meleon should have download manager integrated like Opera.
It is a MUST have. Otherwise, others will use FF or Opera instead and K-Meleon is going to oblivion like Netscape did...

Keep up the good work.
