I made some changes to the postbit, using images instead of text. The original text is now used in the image ALT tag and I have images that are slightly different depending on if it's an add or a remove of the favorite.
The original images were free on the web and I modified them to suit my own website, so change them as you require.
Edit Template: vbfavorites_postbit
Delete everything in it, replace it with:
Code:
<if condition="$show['member']"> -
<if condition="$show['vbfavorites_post_in_favorites']">
<a href="vbfavorites.php?$session[sessionurl]do=delete&entry_type=post&entry_id=$post[postid]"><phrase 1="$vbphrase[post]"><img class="inlineimg" src="$stylevar[imgdir_misc]/favorite_post_remove.png" alt="$vbphrase[vbfavorites_remove_x_from_favorites]" /></phrase></a>
<else />
<a href="vbfavorites.php?$session[sessionurl]do=add&entry_type=post&entry_id=$post[postid]"><phrase 1="$vbphrase[post]"><img class="inlineimg" src="$stylevar[imgdir_misc]/favorite_post_add.png" alt="$vbphrase[vbfavorites_add_x_to_favorites]" /></phrase></a>
</if>
</if>
Place the attached images in your images\misc folder.
