I completely agree for the most part.
Fotolia just made major changes to their site that has left it even worse for flow. I have always believed that they would work things out, but it sure is taking a while. The speed thing has always been a problem.
The few things they do have going for them is a good multilingual setup and a huge database of images. I completely hate the submission system, but continue to submit because the sell a good amount of image. (BTW: This also has fallen off since the new version, but I am confident it will come back up).
