that's not entirely true, he didn't hack into your account and steal your photos unless you set them as private and can only be viewed by yourself, or if you set it so that only people who have the link to your album can see it.
I did a little experiment and found that without an account, you can use PhotoBucket's search option and find lots of photos available to the public for viewing and download:

as I said in my previous message, other members have recommended this and it is
highly advisable for forum members to water mark your photos to prevent photos from getting stolen and used inappropriately by other members or Ebay sellers
