Media Library diagonal alignment fix

In post edit mode, there are situations where the thumbnails in the Media Gallery rows do not align vertically, one below each other, but stack diagonally.
This is rather a WP issue, but anyway it is easy to fix.

media-tags\css\mediatags_style_admin.css somewhere at the end of the file add the following:

/* [alx359] added to fix diagonal stacking issue in Media Gallery post edit mode */
.media-item { float:left; }

As a bonus, if you’d like a little larger thumbnails, add the following line next:

.media-item .pinkynail { height: 40px; width: 50px; max-height: 40px; max-width: 50px; }
