@Josue Salazar: You shouldn’t edit/add any files inside core theme folder ‘catch-flames’. As all these edits will be reverted back to original when you update or upgrade the theme.
The slider you see in Catch Flames theme is the demo images. In Catch Flames free theme, there is option to change this demo images with your Page Slider images. For that, first you need to create pages and assign featured image in those pages. For featured image, check this http://catchthemes.com/blog/videos-blog/video-series-adding-featured-image-wordpress-postpage/. Then, you need to go to “Appearance => Theme Options => Featured Slider => Slider Options”, there in “Select Slider Type” you need to check in “Featured Page Slider”. Then you will see Featured Page Slider options box below, there you need to select the pages and save changes. For more check our theme instructions page at http://catchthemes.com/theme-instructions/catch-flames/
But if you upgrade to Catch Flames Pro, you will have option to change that demo slider to “Page Slider or Post Slider or Category Slider or Independent Image Slider.
