How do I make this?

[justawfulgamer]

Can someone show me how to make this image? I've attempted it with mixed results. I think my methods aren't correct. If someone can show me step by step, then I can replicate it. 

So I basically just need a rectangle with curved edges, then put an image of .the arrow on top of it, then put the text under it.

When I do it, I get some strange stuff happening that's really hard to explain.

Thanks!Pic
