Select 'Home Page' in the left-hand column, under 'General Pages'.
Expand the 'Snap-Ins (Content Area)' section.
Expand the 'Custom HTML' snap-in corresponding to the area of the page in which you want to add your images. If you don't have any 'Custom HTML' snap-ins yet, select 'Custom HTML' in the Available Snap-In Modules list, and click the Add button (the '+' icon).
If the HTML Editor is not already in WYSIWYG (graphical editing) mode, click the 'Switch To WYSIWYG Mode' button. After the page reloads, re-expand the sections you were editing.
Place the cursor where you want the image to go, in the editing area.
Click the 'Image Manager' button, or press Ctrl+G.
Double-click on the 'Images' folder to open it.
To use a new image on your computer that hasn't been uploaded yet: Click the 'Upload Image' tab. Click the 'Browse' button. Navigate to the desired image file (jpg or gif) on your computer, select it in the 'Choose File' window, and click 'Open'. Now click the 'Upload' button. The image manager will reload in the 'Browse Files' tab. Double-click on the 'Images' folder to open it again. Proceed with step 10.
To use an image you've already uploaded: Select the image, and click Insert. The Image Manager will close, and the image will be added to the HTML Editor.
