Im trying to make a post-slider or post-carousel with images from the posts showing. But I need to add the image in the posts by “add media” and not “featured image”. How can I use this image in the sliders/carousels? It seems that all post sliders only use the featured image?
This theme uses featured images for slider and there is no settings to add regular images that are inside post content. The thing is that this kind of solution would require a lot of other settings to make it work with post content images. For example: which image would be shown in slider if you would have dozens of images inside your post? Why to use full size images inside post content if it is around 700px wide but slider is much bigger than that.
There are two possible other alternatives:
Replace slider with some plugin such as Meta Slider.
Create slider manually using a simple HTML and here is an example.
This tutorial for Dazzling theme but the only difference is that instead of looking for <?php dazzling_featured_slider(); ?> you should look for <?php sparkling_featured_slider(); ?>
Thanks mate! Quick follow-up question: My featured images get cropped when used as “featured image”. Where can I change this to be unlimited? (or bigger at least)
I don’t think that you want to change width of featured images as content area is only 750px wide. To get uncropped images just reduced second value (height) to something high such as 9999 now you will get 750px wide images that are never cropped but just resized for performance purpose.
Now you will have to regenerate thumbnails as WordPress won’t for it for you for existing images. For that you can use this plugin. Images that you will add after you have changed values inside functions.php file will resized automatically.
