Hi thetentalents,
If you do not need to keep more than 1 MB of images stored within your account during the month you will be away, you can switch your plan to the Free Marketing Tools plan for that month to avoid being charged. However, if you need to keep more than 1 MB of images hosting in your account, you would need to remain on a paid plan that includes a sufficient amount of image hosting space and would still be charged for that plan during the period of inactivity.
I hope this clears things up. If you have any other questions about this, feel free to contact our customer support team using the form on the following page of our site:
