You will admit that all images don’t look better in dark mode. To match images with the dark mode they need to be in a proper version. Dracula lets you replace light-mode images in dark mode.
Navigate to Dracula > Settings > Image Settings > Image Replacement.
Add a new image group. You have to add a new group for each image that you want to replace. After adding a new group you will find two input fields for entering the image URL.
On the Light Mode Images section, Enter the image link or select the image from your local device that will be shown in the light mode.
On the Dark Mode Images section, Enter the image link or select the image from your local device that will be displayed in the dark mode replacing the light image.
