Hi Bill,
You do have to delete photos to free up space. To do so, go to your photos, make sure you are logged in, click on the specific picture you want to delete, when it opens there is a tool bar named Additional Info below the photo, click on the icon that looks like a computer screen (second from the right), click on that, scoll down a little ways and the is a section with a box you can click on that says...(CAREFUL - once it's gone it's gone),click on the box and then click on the Submit Changes icon...and then it is gone. Or......easier.....you can subscribe to the KitMaker Network and for less than $4.00 a month you get a very large photo gallery. I am a subscriber and I have 103 photos in my gallery and it hasn't even shown as starting to use up any space yet. To get info about subscriptions just log in and click on your username in the upper right corner of the site. You can go from there and it is very simple to do. For the minimal amout of money it is very nice!!
I hope that helps.
Randy
