>1. I need to store some images in a table. To save disk space, JPEG format is preferred. However, it seems that there is no direct support for JPEG in VFP. Anyone with this experience can give me some insights?

You may take a look at different OCXs that might do the job. There is also the FoxPro Developers Tools section in the Visual FoxPro Yellow Pages which contains some image tools.

>2. When I am playing around the form wizard, I find that it do a very good job for generating form for One-to-many relationship. However, it restricts to only 1 parent and 1 child table. Any fast method for 1 parent and multi-children tables?

The wizards are very limited. But, from what is being generated, I think you can move with the generated form and customize it to your own needs.
