The most common problem people run into is forgetting to upload the gif image itself to the same folder as the page with the code. For more details read this post in our forum:

To reacquire your code log into your account here:

Then press the "Change Logo" link.
The reason we require people to host the logo locally is in order to save bandwidth on our servers. The logo is not very big but with several million hits each day it ads up. This way the logo is also presented at the same pace as the rest of the content on your page.
If you don't want to upload the logo to each directory on your site you are welcome to modify the code to point at the place where you have uploaded the logo. Be very careful to not touch any other parts of the code. To modify find the line in the code that looks like this:
target="_blank"><img name="av" src="avitop6.gif" width="135" height="17"
Let's say you have all your images in a folder called images. Then you would upload the selected gif/jpg to the images folder and update the code to:
target="_blank"><img name="av" src="/images/avitop6.gif" width="135" height="17"
Be sure to use the correct gif name. avitop6.gif is just the name of one of our logo's.
Hope that helps. If not you are more than welcome to contact us.
