In Salesforce, editing an app, one option is "Choose the Image Source for the Custom App Logo". When I click the "Insert an Image" button, it pops up a window to add a file from a dropdown "My Personal Documents."
However, I cannot find where to upload an image to "My Personal Documents" anywhere in the Salesforce documentation. Can someone please point me to where to do this?
I am looking for specific instructions like, "Click the Setup link in the upper right nav, then click the ___ link/button, " etc.
ETA: I have found this help page, which starts with "On the Libraries tab," and they have lost me right there. Where is the Libraries tab?
