Looking for a stock photo web system for good look and feel and maximum flexibility. Found two systems like Ktool's Photostore and StockBoxPhoto. Both the system has many visible common features but need to know the hidden differences.

The criteria of evaluation might be:

1. Default look and feel.
2. Versatility, efficiency and speed of search option.
3. Search Engine Optimization performance
4. Limitations of image size, numbers etc.
5. International currency selection.
6. Security.
7. Trend and the Future

Thanks.
