Simple Paypal integration and top align problem.

Good Day!

I have some problems about wordpress and I don’t know how to go about it.

1. I want to link paypal to an image “buy now” so that every time it is clicked, my customer will be paying to paypal and after paying, a thank you page which contains instruction and download button will be available for the purchased file.

2. How can I align top word description in a table. Every time a align top, it just remain center aligned. I even tried editing its HTML.

Please help me. Thank you!
