1. my HD has 250GB limit and do l check "storage" in "system report" for storage space available?
2. does deleting the disk image and emptying the trash, mean l retrieve the space? eg if disk image is 5GB, if deleted completely, l regain that 5GB?
3. why can the password protected disk image be deleted without a secure pw login?

On number 1 Right click on the drive icon, then Get Info. That will show how much space is used and available on the drive.
On number 2, yes.
On number 3, it shouldn't, I think. I haven't PW protected any drive images.

You can right click on the file and select "Get Info". Then click the "Locked" check box.

When you created the disk image, did you uncheck the check box for "keep password in keychain"? If someone has access to your computer and logon, there's not much you can prevent them from doing. Set up a separate account so they can't delete your image by accident.

Password protecting the disk image does nothing to it as a file. In other words, it's still a file like any other. The OS can't distinguish between what is and isn't password protected - it looks like any other disk image. This is why you can delete it without providing any sort of credentials.
