Settings » Media Settings
The Media Settings allows you to control how your media is displayed. These settings can be found on the Settings -> Media page.
Image sizes allows you to change the maximum dimensions of images that are displayed on posts and pages. When setting a thumbnail size, the image will be cropped and resized to the setting. Medium and large images will keep the dimension proportions, taking the maximum width and height into account.
Some of the previous settings for defaults have been removed. WordPress will now save the state of those settings from the last time you used them. For example, if you last inserted a full size image, that option will be set the next time you insert an image.
You can use the ‘Limit Width’ option to specify specify the maximum size for the player. We currently support auto-embeds from YouTube, Twitter, Vimeo, Viddler, Blip.tv, and Lytro, though videos from select other services can be embedded following the linked guides on the Videos page.
Image Gallery Carousel
The Enable carousel option allows you to turn the feature on or off for the chosen site and select whether you’d like to use a tiled mosaic-style layout (a thumbnail grid layout is the default).
The Background color option allows you to switch your site’s galleries to using a white or black background for the Carousel display (defaults to black).
The Metadata option allows you to turn on/off the metadata information shown in the Carousel.
Video player gives you the option to display videos that are only in free software formats.
