Well the image degradation is quite obvious but I agree to your wider point, that said R2R could theoretically disappear too. The only way to be sure that ones images are always available is to host them oneself. Compared to the cost of a aquarium or a decent camera then website hosting and a url are pretty cheap.
Yeah, I would never use a hosting service for the purpose of storage... I store every single original on my computer or external hard drive. I just use the hosting service for the ease of sharing.
