Web site for a local photographer

You are creating a new Web site for a local photographer. The photographer asked that you determine methods to help his Web site load quickly despite having so many large images. To this end, find information on using thumbnail images. Review other photography Web sites and create a list of "suggestions" for loading large images. Additionally, search the web for information on adding useful, descriptive alt attributes for images (this is very important). Write a brief synopsis explaining the information that you found in your research.
