Step 1: Create the Library (Do this once)
On the left sidebar, click "Your Stuff".
Click the (+) or "Create" button near the top of that panel.
Choose Library.
Name it: "Project Name Assets" and click Create.
Step 2: Save the AI Images to that Library
Select the AI landscape image on your canvas.
Right-Click the image.
Select "Add to Library".
A list will pop up—select your new "Project Name Assets" library.
Repeat this for all images and your logos that you need for that project.
Step 3: Access them later for the next part of the project
Open your new project.
Click "Your Stuff" on the left bar.
Click on the "Project Name Assets" library.
Drag and drop your images right onto the timeline if it's a video (or other for flyers, etc).
Use this if your school internet is glitchy or if "Libraries" are blocked on your student accounts.
Sometimes, school enterprise accounts lock down "Libraries." If the method above doesn't work, then just do this:
Select the image on the canvas.
Right-Click > Save as Image (or click the Download button at the top right > PNG > "Selected Page").
Save it to your computer's Downloads folder.
Just go to Media > Upload from Device when you're ready to use it
