Bob,
You do not need to put anything in the 'contains' field. Click 'Show all Images' and proceed from there.
To add:
- Click "Show All Images"
- Tick the small “Image” click box
- Select which images you want to bulk edit or, select all your images by clicking the small tick box.
- Click the gray bar "Edit checked images simultaneously"
- Adjust your prices under the appropriate category
- Be sure to ‘Submit’ when complete
