Are Tables considered valid xhtml? I thought that was the point with reduced code via css positioning?
No tables are still valid tags, the point of xhtml is to create an XML based version of the older HTML 4.01. Tables are still useful, very useful for tabular data. Therefore, tables cannot be dismissed.
@P4L he said he was using XHTML 1.0 strict, not HTML 4.01. In XHTML 1.0 all tags MUST have a closing tag or be self closed. Again, this is since it is based on XML, and all tags are closed in XML. Therefore, <img src="images/something.jpg"> is invalid in XHTML.
@edu2004eu are you using the correct doc type? or is it all going into quirk mode? I actually never used strict mode before, try using Transitional mode instead. You might also want to read this:

In general, the slices photoshop gives you and the code generated aren't really the best, far from it. You might want to use some <div> tags instead of tables for your page layout. Makes for much nicer and maintainable code.
