Often, hosting providers will offer you a free trial period which you can utilize in order to get acquainted with the server and the provider as well. You should try to find out the length of the trial period and use various programs in order to track relevant statistics related to the server such as responses and server uptime.
Photo hosting providers usually have free and paid plans, so you don’t even need to pay to use them. Unfortunately, your clients will be paying the price for it by seeing ads when browsing your portfolio. It might be okay for a beginner but does not look very professional. If you get a paid plan, you will be able to use the provider's interface only without the ability to install something else.
As you can see, a VPS can be the perfect middle ground for many – enough flexibility and resources for those who need more access or control than on a shared server but without the cost of a dedicated server. If you need root access, you can’t get that on a shared server, but you can get it on a VPS. If your site experiences unpredictable swings memory usage, and your host provides it, then the presence of burstable memory will be attractive. And, if you’re a fan of customization, then the fact that you can customize server-level software such as PHP, MySQL, and Apache will perk your interest.  In short, choosing a VPS will allow you to have many of the same characteristics of a dedicated server but in a more affordable and manageable package.
