How do you make an image that can be updated without changing the html code?

I know people have done it. I want to know how to make it so that if i want to change a picture to update itself when i have a newer pic people who have it linked don't have to change the html code. Like a club penguin tracker!How do you make an image that can be updated without changing the html code?
Just make sure the new one has the same name (like Image.jpg) and upload it to the same folder. You'll over write the old one, or you can change it's name first.How do you make an image that can be updated without changing the html code?
just over write the original file it has the same name and address so you don't haft to chance anything
All that's in the HTML file is a link to the image file - there's no picture in it. If the picture location stays the same, and the name of the picture file stays the same, you don't have to change the HTML file.
Go to www.w3schools.com and look up asp

that's what you want to look at
You could just overwrite the image.



Or you could go to gaiatools.com and sign up to make a random signature. Then you could upload the image you were wanting to, then just delete it and add the new one whenever you change it. And apply the code to your blog or website.



Sorry, if that is confusing.
