My iCloud address on the iPad needs to be changed. If I press "delete account" it tells me I will lose all the content including pictures. How can I change it? I see other people have had the same problem

Question

I have had to change my e mail address but I cannot work out how to amend it on my iCloud account. If I press "delete account" the box appears telling me that I will lose all content including photos if I continue. The box asking for a password keeps appearing but I just press cancel and continue.
I have not attempted to upgrade to iOS 7 until this problem is sorted. Can anyone help please?

If you mean that you created a new icloud account using a new email address as the primary address, then when changing to that account on a device, all data maintained by the old account will be deleted.  I was not aware that photos are included.  But as for photos, ALWAYS sync them to a computer for archiving, never rely on icloud as your only backup.
If you want to keep the contacts, etc. data from the old account, then go to Settings>icloud and turn off the services, one at a time.  When doing so, you are given the choice to keep the data local or delete from the device.  Later, when doing Delete Account and logging into the new account, your data will sync up to it.
If, on the other hand, your changed email address is just an alias in the existig icloud account, then there's no reason to delete the account as the alias is just another link to the same account.
