Hi, Lego! :) I posted a suggestion about your problem with slider on private message in chat, but you left. And so, just in case you missed it, I am leaving it here: would you try adding display:inline-block in portal_sliderlink div tags in Slide/Main? Specifically, like this: <div class="portal_sliderlink_2" style="width:300px; padding:1px; margin-left:auto; margin-right:auto; box-shadow:0 0 1em #333; text-align:center; display:inline-block">[[File:Rsz books.png|300px|link=Template:Slide/Books]]</div>. I am not too sure if it will work very well or not since I am not too familiar with the slider template and I have not looked into it enough either, so I can not guarantee it is the valid solution - but do try giving it a test and let me know if it works.
