Where to store assets for multiple web apps

I am working on a project that is consisted of multiple web applications communicating through some messaging system. Those applications need to be looking at some assets like images and so. Is storing images in MySQL database as blobs a good idea? or should I be using another tool.

Notes:

• I cannot use a hosting server because it's not guaranteed to have internet connection where the applications are deployed. Thank you.

• Applications are to be deployed on different machines.
