Bud, a computer monitor generally displays your pictures at about 72 dpi. but your file size dpi is what a printer is going to print at so a 700 dpi print will have 700 dots per inch on paper, but if you attempt to put a 700 dpi file on the web your monitor is still going to display about 72 dots per inch of actual screen space so a 700 dpi file will display at almost 10x on your screen. so if your files are larger than 100 dpi you will want to resize the file to 75-100 dpi for web display but you will want to keep your original file at a higher dpi for printing purposes.

John, Gary, Dave or Paul or Tim will come along soon and explain it a little better soon.
