# Image troubleshooting
Images are displayed in different formats across Marfeel. In this article you will find image related issues and how to solve them using configuration flags.
# Secure media (https)
If no images display and the tenant is using http, it might be because by default Marfeel forces all media to load through https.
To keep the original src of the images, use the enableUnsecureMedia flag.
# Image reverse proxy
Image reverse proxy, enabled by default, activates proxying for all the images in the page.
This means images will be optimised and served from live.mrf.io environment.
Depending on the tenant configuration, this feature can result in issues such as blurry images or not displaying at all.
When necesary, disable it using disableImagesReverseProxy

To display an article as an image gallery, use the forcePhotoArticlesByUrlPattern flag.
# Images in sections
Configuration for images in sections depends on the extractor used.
