OK, regarding my second query. This is what I've done.
I opened the template "blog_navbar_link" and here found the following code:
Code:
<li><a class="navtab" href="blog.php{vb:raw session.sessionurl_q}">{vb:rawphrase blogs}</a></li>
Then, I changed it to this:
Code:
<li><a class="navtab" href="blog.php{vb:raw session.sessionurl_q}"><img class="inlineimg" src="http://forums.pakfellows.com/images/icons/Homepage/blog.png" border="0" />{vb:rawphrase blogs}</a></li>
This inserted the image in the correct place (see screenshot), but I would like to have it so that the word "Blogs" remains in the center of the tab, i.e. both image and text are inline instead of Blogs being pushed down. Any help please?
