I just made a small change to the picture search you use to find pictures on Flickr. Previously it had found pictures that had ANY of the tags you provided. Now it finds pictures that have ALL the tags. This is what I intended all along but I got it wrong in the Flickr API. Now it is fixed.

So, suppose you’re looking for a picture of an apple still on the tree. The comma separated tags apple,tree,leaves finds a good selection of relevant pictures.

Another example. If I search for blue bike (note no comma) I get 4 pages of pictures. If I search for blue,bike (note the comma) I get 118 pages of pictures. The first query requires a single tag with the words blue bike in that order. The second query requires the tag blue and the tag bike in any order.
