Hi Corey,
Balls! - I made a mistake, sorry... I can see you implimented what I told, unfortunately it should be..
#page-content #DDSliderCont ul li {
padding-left: 0;
}
Sorry bud, I was responding via my phone while being bored in a meeting.
Regarding your second issue, again it's down to CSS. The div generated by ddslider is floated left (#DDSliderCont) to make parts of the slider work properly, your content is not floated or wrapped as wordpress wont apply those kind of elements to your content by default.
You would be much better off creating a template page for this gallery page and then placing the slider in the template used for this page using the php tags, something like...
<?php if(function_exists('displayDDSlider')) {
print displayDDSlider(array('name'=> 'MY_GALLERY_NAME'));
} ?>
You can then place the slider outside the content div and the two shouldn't effect each other as much.
Hope that helps!
- Matt
