for your image tag errors, you can knock of a bunch of those other errors simply by closing the image tag.

<img src="whatever"> SHOULD be <img src="whatever" />

I had 56 errors on my site, i fixed an image tag like that and was left with only 6 validation errors which are simple fixes simply because they arent valid for my doc type.

Also, i notice this

Error Line 2700, Column 218: an attribute value literal can occur in an attribute specification list only after a VI delimiter.

…is feed Off Topic "Non-Diesel Related"" /></a>

Im willing to bet if you remove that extra " more errors will disappear also.

EDIT
I just noticed you do have img tags closed properly, just mkae sure they are ALL like that, and try removing the extra " like I mentioned. its confusing your code.
