For adding slider. There is super easy way to add slider with post images to post. Add any pictures from standart WordPress uploader.
You can add many photos at once, just hold Ctrl. When you upload pictures, don’t insert them in post, just close popup.
Click on shortcode button. Choose slider from post images shortcode in media section. Click to insert. And, it’s wonder. All images that you uploaded from post will be in slider.
Note, slider generates images with large size of pictures. You can change this size if you need on page Settings Media . Width of post content is
765px, so I recommend you to use it. And I like
400px height, but you can add any height.
For easy adding carousel of specified images or slider
Click on standard Add media button of WordPress. Choose Create gallery at left side, make gallery and insert it in post. No matter what gallery settings you set, so leave it by default. Then, go to text view of visual editor. In place where you added gallery you will find code like:
wpsm_quick_slider if you want slider gallery or to
wpsm_minigallery if you need carousel, example:
