Images and Files
While configuring your text editor with TinyMCE there are several tabs for settings related to file and image uploads.
The image browser allows a person using your website to select an existing image from the files directory.
Checking this option gives you access to the file browser. If you only check this option, you will ONLY be able to access images that have been previously uploaded.
You must check this to allow people using the text editor to upload images directly into your text field and add them to the image browser, if the image browser is also selected.
If you have enabled the image browser and image uploading, you will have both options available.
(Someone, please provide information on what this setting does.)
