Use different size images for testing alignments

[joyously]

I never thought it would happen, but someone wrote a theme with CSS specific to the unit test data, which makes the image alignment pages look okay even though the standard WP classes were not defined.

Remove the CSS that is specific to the unit test data:

.content-page .alignleft{ width: 150px;}
.content-page .alignright{ width: 300px;}
.content-page .aligncenter{ width: 580px;}
.post-content .alignright{ width: 300px;}
.post-content .aligncenter{ width: 580px;}
.post-content .alignleft{ width: 150px;}

It would also be good to test large images aligned left or right, and large captioned images centered.

Would you believe there was another one!?
