ok...i have a font on my pc that i want some parts on my website to appear typed in....but idk how to do it...

for instance if the top of the page said "introduction" I want it to appear to be in a sloppy graffiti type hadwriting....so would I have to make it a picture? and then link it?? or could i just type in a graffiti font...

i didnt think the people who dont have the font on their pc would be able to see it...

You'd be right--people who do not have the font on their computers will not see your text in that font, so yes, you would have to make a graphic out of your text in order to have it appear in that font.
