How to use Joomla Media Manager?
In order to fully utilize the multimedia capabilities of Joomla, you can start using the Media Manager utility. You can find that in the SiteDirectory drop-down menu.
Under the file and folder list, you will be able to see three input boxes:
[Upload] allows you to select file and upload it to the image library (using the [Browse] button and then clicking the [Upload] icon in the top right corner).
The Code box displays the HTML code that allows you to link to the image from the library you have clicked on.
Through the Create Directory box you can create a new folder to which you are able to upload files. Type in the name of the directory and then click the Create icon at the top right corner menu.
In order to be able to upload to a certain directory, please click the folder image, under which the specific name appears:
the page will be refreshed and you will be able to upload directly to the respective folder.
If you'd like to delete a file or an empty folder, you can click the Trash can image below the item you wish to delete. You will be prompted to confirm deletion.
Please note that in case the directory you are trying to delete is not empty you will be unable to remove it.
