Something I do when looking for graphics to put on a web-site is use the Google or Yahoo search page, click on the "image" search button, then enter terms such as "cash", "money", "success", "achieve", "internet", etc... Web-pages come up in the search that have very interesting and useful graphics on them that I "right click" and then "copy", or "save picture as..." and thus I build up a small library of graphics to use. With the billions of web-pages online the graphics available are amazing.
