I notice that not all images get downloaded.

For example: <http://www.pintura.aut.org/SearchAutor?ApodAut=A?SinLimite=1> a
list of peinters, with htm pages, and small jpeg files can be downloaded.
<http://www.pintura.aut.org/SearchAutor?Autnum=16.575>
<http://www.pintura.aut.org/SearchProducto?Produnum=115322>
<http://www.pintura.aut.org/BU04?Autnum=16.575> all ok.

but after the files:
<http://www.pintura.aut.org/SearchProducto?Produnum=115322>
<http://www.pintura.aut.org/Obra.html>
(http://217.75.242.165:8080/4DPict?file=20&rec=115.322&field=2) , The program
can´t find the link for. I´ve tried many rules to get the big jpeg images,
but it´s impossible. 
Some of the jpeg images turn up as html files, and many others, who are in
other site don´t appear. 
the trouble seem to be the number of the picture, after =,xxxxxx, can you help
me ?, please. 

Sorry for my bad english.
Otherwise it is a perfect program.

Thank you for creating it.
