Issue with Chrome

I found a issue with the thumb rotation with the chrome Browser.

Normaly we had a set of thumbs for the rotation like this:

In that case the rotation in chrome works well. But we also have a lot of old Videoposts without http://domain.com/bilder/thumbname-0.jpg

The rotation starts with 1 and goes on up to 10 / 0 . If the thumb -0.jpg is not availible then the user see the error which dont looks good.

On the site Blowjobvideos.biz i had renamed the last thumb for the first six videoposts („NEUE BLOWJOBS“). The change was to remame http://domain.com/bilder/thumbname-0.jpg to http://domain.com/bilder/thumbname-x.jpg

Here is a video to discribe it:

A solution would be to limit the rotation 1-9 in instead of 1-10. That would reduce the errors a lot.
But much better would be to detect if there is no further thumb and quit or something else, so the user does not see the error. That is what i would prefere because we had a lot of old sites and posts where we just have one or two thumbs insteed of 1-10.
Here is a example:
I deleted here the following thumbs and there is just the first:
For the view of a user it looks very bad as you can see.
Maybe you  know a solution for that, with firefox that is not a problem. Perhaps there is a special solution for Chrome (E.g. Chrome dont support mouseover or something else)
Ps.  You will find the script for the rotation in this path:
