>Do you have a fast broadband connection? It took about 1-3 seconds for all photos to load on mine. That is typical of the banking site I use. It uses a single photo as a 'pass key' in addition to the login and password and it takes about the same amount of time for the single photo to appear on its site.

>I did comment on the one login where there were more photos. My concern was not that it took too long for the photos to display, but that it would take too long for the user to have to focus on each picture to determine how many of the concepts were in the photo. It may be too frustrating to users when there are more than just a couple of photos.

I have DSL but it is not very fast (according to my test with speedtest.net). And I also have one-picture pass key when doing online banking. And when I do online banking it loads the picture fairly fast. At least I didn't feel it was taking too much time. But it was (perceptively) too long for me to wait for the several pictures to load on this test site. It could be my connection but it could be also the way PHP site was working.

And I also commented on the speed being a concern. I believe there should be a better way to authenticate using text (words instead of pictures).
