It's all a question of asking yourself, will the images and content you have posted in the past in this and other forums worth the trouble of moving them out or the money you will spend in acquiring this new plan? Consider also that you do not know how much they will charge you in the year 2, 3, 4... and so on!!
I have a Website and for the first 2 years they charged me a low value and then when I was already hooked, they raised 2 times that value!
For me, that follow the contents here on a regular basis, it's a loss if I can't see the pictures of your past threads!!
