Can't open attachments on my Nokia 550

[Windows Central Question]

I have a Nokia 550 and I please need to know how to install apps to open attachment formats specifically JPGS, JPEGs, MP4 files. And also what apps do I need and where do I find them.

These file formats are handled automatically on the Lumia 550. I assume that's what you meant by 'Nokia 550' in the first place. You don't need additional apps.
