Problems with W3C validation

Hello,

I have bought this product (dynamic gallery pro) and it works well but I’m getting these W3C validation errors on http://relief-from-pain.co.uk/product/relieve-back-pain/:

1) Line 213, Column 172: Element style not allowed as child of element div in this context. (Suppressing further errors from this subtree.) …al();});});})(jQuery);</script> <style>.ad-gallery .ad-image-wrapper{}#gallery…

2) Line 224, Column 321: Attribute alt not allowed on element a at this point. …m-pain.co.uk/wp-content/uploads/magnehealth_merino_topper_on_bed.jpg”><div><img

3) Line 224, Column 321: Bad value gallery_product_1200_402 for attribute rel on element a: The string gallery_product_1200_402 is not a registered keyword. …m-pain.co.uk/wp-content/uploads/magnehealth_merino_topper_on_bed.jpg”><div><img

4) Line 225, Column 265: Attribute idx not allowed on element img at this point. …vailable in 4 sizes” class=”image0″ width=”105″ height=”105″></div><li

I am getting these for all product images I have added so I get lots of errors.

Please can you help me resolve this or suggest a woo gallery that doesn’t cause these errors.
Many thanks
Guy
