# Uploading content

Now that you have a registered player that you control from your account we can start uploading content that we want to display on the player. For this we will need to go to the "Medias" tab, and click on the "Upload Media":

![](/files/-M_LHISawoPQbJL-P0qE)

A modal dialog will open allowing you to choose which files you want to upload:

![](/files/-M_LHpwv63g5nlZ5px-L)

{% hint style="info" %}
Castmill supports most known image, videos, PDFs and audio formats. If you find a media file that is not compatible, please [contact us!](mailto:support@castmill.com)
{% endhint %}

For this simple guide we will upload 1 image:

![](/files/-M_LIj59Va9XC9Th71I7)

As soon as the image is chosen it is uploaded and will appear on the Medias table.

Now we have an Image and a Player, but we need to still create a Playlist before we can show the content on the Player.
