Hi @rokasjrokas,

I hope you are well today and thank you for your question.

Could you please share the page URL from your site where it is displaying so that I can help you?

Best regards,

I have a gallery slider and problem is that the quality of photos are very low. How can I fix this? I don’t have any other plugin apart Javelin recommended.

Please try regenerating thumbnails on your site using the below plugin.

Second question, how to change the color of those slider dots.

You can change their color by adding the following CSS code in the Custom CSS code option of your theme on the below path.

Admin Area -> Appearance -> Theme Settings -> Custom Code -> CSS Code

#page-container #content .slick-dots li button {
    background-color: #ff7ec7 !important;
    border-color: rgba(54,54,54,0);
}

#page-container #content .slick-dots li.slick-active button {
    background-color: #ab698e !important;
}
