Normal image storing or mySQL blob?

Question

i'm programming a php/mysql web app which is kinda like a blogging platform where people can upload pictures and post them.

What is the best way to store these images , Storing them in a folder or in mySQL table through BLOB ?

i ask this because i want the most simple way which let me easily move to another host/server without spending days to download all posted pictures , and upload them to the new server.

Optional Question: Is a dedicated server enough for a started blogging platform?

Thanks

Out of the database. When it's out of the database your webserver can do its job and make clients cache the images. Doing so with a database-driven dynamic image is more complex. Additionally, you'll find you'll likely get much better performance by allowing the webserver to deal with it.
