Thanks for the replies.
After starting this thread I switched to Firefox. I have been using it now for a while and I must say that it's much, much, much better than the horrible IE.
I also found the ultimate solution for my problem. It's the add-on called "Favloc" that works best for me.

What it does it that it allows you to set up a list with folders to which you can very easily save files from the net. After right-clicking on an image you are no more than2 clicks away from having saved your image in a specified folder, with the certainty of the image having a unique filename. --> If an image with the same filename allready exists the add-on will automatically rename the new image and store it, without you having to confirm anything!
Best solution for porn-browsing ever!
Highly recommended!!!!
