What and where is top-highlight.png?

I discovered it in the stylevars. I think it was from a previous iteration of vB4x.

There is no image named this in the default vBulletin 4.2.X package. Something in your style is looking for this image in the /images/misc/blog folder. You should upload a blank image there to remove the error messages.

Have checked your server to see if this.png exists and if not add 1 as a test.

My server is giving me a lot of error messages relating to a single *.png image.

Example:

[Tue Oct 15 17:43:08 2013] [error] File does not exist: /home/www/vhosts/mysite.co.uk/images/misc/blog/top-highlight.png, referer:

All the error messages are the same, they all relate to top-highlight.png.

What is top-highlight.png, what does it do, and does anyone know why I'm getting these messages?
