Thank you for your reply!
I was able to get it working through the GUI, thank you anyway

but now there is another problem I have
I want to download pictures, some of them are named 1.jpg 2.jpg etc. other
ones are named i.e. th_a th_b. all pictures are in the same folder, how do I
throw the th_a, th_b etc. out?The filter I used
+content.someweb.com/*/*.jpg
-content.someweb.com/*/*[th]
or
-content.someweb.com/*/*[t,h]
not working, what am I doing wrong?
