Is it better to code like so:

Code:
<img src="file.jpg" alt="blah" title="blah" class="alignright" />
...and have a class in the css file that aligns it right, and pads it, styles it etc accordingly.

or:

Code:
<img src="file.jpg" alt="blah" title="blah" align="right" hspace="10" vspace="10" />
They both validate, and the latter option displays better when your content is syndicated as it's likely not connected to the stylesheet in your reader (well, $100 says it's not ).

What do you reckon, oh wise and worldly SP gurus?
