I think it would be nice to be able to see in the Monitor tab at what level the followed links are at the moment when the connections are analysed and downloaded.
If you start a project with no limits of the levels to follow links I believe you can expect to find the pictures your looking for within maximum 4-5 levels down. Further down I wouldn't think there are pictures that are relevant for your search.
So if it is possible to see in the Monitor Tab when the program has reached say level 7 or 8 you know that you can abort your search/download because there is no use to go any deeper.
At the moment you have no idea how far down in the link structure the program is...
My suggestion is to add a column under the Monitor tab which displays the current level for each link...
