i would like to grab images from a site...
the site structure is something like this 

www.somesite.com/gallery/foldername/image1.jpg
www.somesite.com/gallery2/secondfoldername/image2.jpg

www.somesite.com/gallery03/anotherfoldername/image3.jpg

when i try to put filters as 
-*
+www.somesite.com/*
+*.jpg*[>50]  // to eliminate thumbnails

it only downloads the images at www.somesite.com homepage 

please tell me wat is wrong...
