Flickr Advanced Search NOT So Advanced!

First time in my life I had time to search photos on flickr,
I usually upload the photos I take via cellphone.
Until today I really didn't mess with their search engine, but I must say that I am very disappointed! 

Today I was trying to see photos of Aurora Borealis (northern lights)
all the results to my search was 640 x 480. 

I personally ignore these type of images. It might be the most beautiful piece of art, 
if it is smaller than 1280 x 1024 it really doesn't matter how nice of work the photographer did,
it is just piece of junk for me. 

I use 40" Sony Bravia as my monitor and It really is not pleasant to view tiny images on this resolution. 

Back to the topic, Flickr is the best image hosting site there is; but the advanced search on Flickr does not allow to specify image size when searching for images. In my opinion this is a big drawback when you really search images.

I am a member of Easynews newsgroup and their search is the most "advanced" search I have ever seen on the web. I can specify dimensions, put minimum and maximum file size. 

As the best of the best, Flickr should address this little problem and make their "advanced" search really deserve to be called "advanced"
