Adding an Image
You can add an image to a HTML Content Area
i.e. In Message Templates, Blogs, Product Full Description, Catalogue Description
Open the respective editor in the Admin section
In the Rich Text Editor
1. Click on Insert Image
2. When adding an Image you can use the RoxyFileman to upload a file
Click on Add File then Select a file to upload
When the file is displayed Double click the file to insert the image
Note: images are not actually inserted. The image is inserted by a HTML Link.
For someone in the world to be able to see the image then you need to provide a full path.
By default when you insert an image via the editor it only puts the local path
You can see the image becuase it is relative but no one else can see the image
You need to edit the URL and add the website domain
