The Library tab provides the ability to reuse files that have already been uploaded into the system.

Click into the text editor.

Click the Media button in the toolbar.

Click the Library tab. This will display a thumbnail view of all of the files in the Media Library.

You can filter on quite a few different properties.

Here in the example, we're filtering based on the file name. Enter part of the file name and then click the Apply button.

A filtered list of results will appear.

Select the file you want to use by clicking on it.

Click the Submit button.

You'll be moved to the display settings screen.

Display As field = select the desired display (Original is shown in the example).

Alignment field = select the desired alignment (None is shown in the example, this will default to a left aligned, inline position).

Alt Text field = if you don't have any alternative text here, you should.

Title Text field = enter some optional text to be used as a tooltip, if desired.

Link Image field = if you would like to link this image to something, enter the full URL here.

Click the Submit button.

Once the node is saved, if you've attached a link to your image, test it out.
