Each user gets 20MB of disk space. There is A max limit of 5MB per file. This means you can upload 5(Five) 5MB photos to reach the limit. You cannot upload 1 (one) 20MB file. You must upgrade your account if you want to increase your accounts file capacity . Upgraded accounts get A additional 100MB of space, with the file limit increasing to 50mb. If this is still not enough you can of course purchase more. Contact me on the site for information on how to upgrade.
