How to change slider images

@Leanvdm: For Catch Base Free theme slider, check out theme instructions at http://catchthemes.com/theme-instructions/catch-base/#featured-slider

You can see that in free version, you have option to replace that demo slider with Page Slider. For that you need to go to “Appearance => Customize => Featured Slider Options => Select Slider Type” and select “Featured Page Slider”. Then you you can select pages in Featured Page #1, Featured Page #2, Featured Page #3 and Featured Page #1. If you want more then 4, then you need to change the number in “No of Slides”. After you change the number you need to refresh your customizer then it will show you more page selector. So, it will take the selected page featured image. So, if you add 4 pages, then it will show 4 sliding image and so on.

@Leanvdm: Please post in your site URL and also let me know that do you want to remove both title and text in the slider.

@Leanvdm: In free Catch Base free version, you have option to use only Featured Page Slider which will take featured image, title and text from your page. So, the only way to hide the text in the slider will be to add in the following css in “Appearance => Theme Options => Custom CSS” box:
#feature-slider .entry-container { display: none; }

You might also want to check out Catch Base Pro which has option to use Featured Image Slider, which you can just upload the image as per your need. There are other additional features as well, which is listed in theme instructions page at http://catchthemes.com/theme-instructions/catch-base-pro/

@danuska: Sorry I don’t get it what you mean. Can you explain in detail with reference to your site URL.

@kgapo:
1. About the slider that default image. That image will be there if you don’t have featured image in those selected page/post in your slider. So, can you check this screencast at https://catchthemes.com/blog/videos-blog/video-series-adding-featured-image-wordpress-postpage/

2. If you want your sample page to be your default home, then you need to go to “Appearance => Customize => Static Front Page” and then in “Front page displays”, you need to check “A Static page”, then you need to select that sample page in “Front page”. Finally Save and Publish it.

@kgapo: Did you add featured image in your page Ποιοί είμαστε. If not then first add that featured image in that page. After that you need to go make change anything in customizer to clear the cache and see the changes.

I will also email you to help you in this process.

@grahama: I see there is featured image in your page but the image size is small. You need to upload image size of at least Width: 1200px Height: 514px.

ALso can you advise how to remove the grey text from the default slider or tell me how to fix my issue please.

@grahama: Please add in your site URL and explain that are you trying to do. When I check in your site http://proencltd.com/, you haven’t added image. For more, check out theme instructions at https://catchthemes.com/theme-instructions/catch-base/#featured-slider

@whiteavenger80: In Featured Post # 1, # 2, #3, you need to add in Post ID. For Post ID, you can refer to plugin Catch IDs https://wordpress.org/plugins/catch-ids/

If you don’t want to add manually IDs, then you can just create category and add in posts in those category and in Slider Type you can select “Featured Category Slider”.
