Validation error shadow.png

Hi everybody,
This is a great slider!
I have one problem though. It gives 2 validation errors.
-Element style not allowed as child of element div in this context. (Suppressing further errors from this subtree.)
– An img element must have an alt attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

I tried to change that, but can’t solve it.
if somebody knows how to solve this, please let me know.
Here you can see the validation errors: http://validator.w3.org/check?uri=http%3A%2F%2Fwww.tina-turner.nl%2Fblog%2Ftimeline%2F&charset=%28detect+automatically%29&doctype=Inline&ss=1&group=0&user-agent=W3C_Validator%2F1.3+http%3A%2F%2Fvalidator.w3.org%2Fservices#line-250
