The “name” attribute on the “img” element is obsolete. Use the “id” attribute instead.

The “cellpadding” attribute on the “table” element is obsolete. Use CSS instead.
The “summary” attribute on the “table” element is obsolete. Consider describing the structure of the “table” in a “caption” element or in a “figure” element containing the “table”; or, simplify the structure of the “table” so that no description is needed.
The “border” attribute on the “table” element is obsolete. Use CSS instead.
The “valign” attribute on the “td” element is obsolete. Use CSS instead.
