You will only be able to add / remove images while logged in to your site and in the page editing "mode." For instructions, visit this page.
Underneath the Body section (where you edit the content of the page) you will see an area for uploading an image to your page (green box). For instructions on how to add / edit files, visit this page.
Click the "Choose Files" button to open a window where you can find and select the image you want to upload. Once you have selected the file, click the "Upload" button and you will see your image appear in the Image section. You now have a few options for inserting the image.
We recommend you use "Automatic" style for inserting an image into a page. After selecting the size that you would like to use, click on the "Insert" button and you will see the image appear in the page Body section. You can now select the image to adjust its size, alignment, etc. using the formatting toolbar.
If you need to remove an image from your page, you can simply delete it in the Body section.
