Slider

@Sarah: For image to become same size in the slider. You image size should be minimum Width: 644px and minimum height Height: 320px.

For some of the old images that your site have before changing to Catch Box Theme, you need to regenerate thumbnail. You can do that by adding “Regenerate Thumbnail” plugin. See the theme instruction at http://catchthemes.com/theme-instructions/catch-box-pro/

@Simon: In your site, you have different length of text and that is causing shifting in height. I see that you have split content using more tag <!--more--> in your page. So, you have to be careful about the amount of text that you want to display. If you keep excerpt text length in all slider page then it will fix the issue. Otherwise, you can try adding in the following css in “Appearance => Theme Options => Custom CSS” box:

#slider-wrap .featured-text { min-height: 75px; }

@Dhuan: Please post in your site URL and then I can check it for you.

@Dhuan: Are you using Catch Box Free theme, try adding in the following css in “Appearance => Theme Options => Custom CSS” box:

#content nav#nav-slider {
    display: none;
}
#content #slider:hover nav#nav-slider {
    display: block;
}
