Getting images from web is so easy, we tend to forget someone created image and should be paid for use of it. The first thing you should do when considering using one, is getting permission from creator/designer of graphic or image.

You have to read user agreement carefully before using images offered by some websites. Most of time, they are free for personal use but must be purchased for business use.

There are many distributors of commercial graphics and images catering to needs of Webmasters. Some come in sets of multiple indexed CD-ROM's with a searchable database.

Another good source is return bin of retail computer goods stores, such as: CompUSA, Fry's and so on. I've found huge collections of commercial graphics for next to nothing because somebody opened package and brought it back for a refund.

Likewise, your digital camera can be a source of royalty free images. A word of warning: You still have to get permission from owner of any commercially protected product you photograph; just because you photograph something doesn't mean you own all rights to image.

The most common font used for print ant Web is Times New Roman. This is default font of many applications including most of Microsoft Office Suites. That is not to say it's most readable or comfortable font; on contrary, Arial, Courier and Verdana are considered more readable.

A study conducted at Wichita State University in 2002 titled: A Comparison of Popular Online Fonts: Which Size and Type is Best? found these amazing results:

Times New Roman was deemed least preferred font in 10 or 12 point size.

Arial was most preferred in 12 point size and Verdana was most preferred in 10 point size.

Overall, Verdana was most preferred font for readability and ease of comprehension.

The fonts considered most legible are Arial, Courier and Verdana.

As far as looks, Times New Roman and Georgia are preferred over others.

All above appears to imply that for design choices, like when a large font is used as a decoration, Times New Roman or Georgia is choice.

For general speed of reading and less strain on eyes it's Arial if using a small font.

Verdana was choice for best compromise between legibility and speed.

All above should be included in building plans for your website since they can affect looks of so many items, such as: Headlines, header tags, choice of colors, links, contrast and decoration.
