Please let me know if you have a go with the image downloader.  I hope you find it useful.

If an m file in matlab is to be a function, then the (uncommented) line in the file must start with the word "function" to define the function, thus by adding

Names{1,1}='hendrix';
Names{1,2}='joplin';
Names{1,3}='the_eagles';

you have generated an error.  You should either put those lines in at the command prompt, before calling  "downloadimagesfromgoogle(Names,1,1);" or you could move those lines inside the function and remove the Names parameter from the function, such that the first few lines of the m file look like this:

function downloadimagesfromgoogle(start,finish)

Names{1,1}='hendrix';
Names{1,2}='joplin';
Names{1,3}='the_eagles';

then you would simple call downloadimagesfromgoogle(1,1) from matlab.  I would suggest using the first method, as that was the way in which the script was intended to be used.

Don't worry about there being too many images.  Google only caches the first 1,000 or so images, 910 in fact for jimi hendrix.  (http://images.google.co.uk/images?q=jimi+hendrix&ndsp=20&svnum=10&um=1&hl=en&rlz=1T4GZAZ_en-GBGB228GB228&start=900&sa=N) even though it says there are hundreds of thousands.  However, if that is too many it would be easy to modify the script to stop at whatever number you want.  Let me know if you cannot do it.

Sorry for not replying sooner, I missed your post.

I had a quick look at doing what you wanted and posted the code here.  I have not tested it.  Let me know if it works.  You will need to log in to see the file.
