Paint.NET

Need help creating the following photoshop effects for instance chrome effect

You have posted many images with many effect in them, which one?
The last 2 is the easiest to make in PDN. (Hint: the make a wave Tutorial)
Chrome is not too hard, just need to make the texture.
Hard part is making the shape.
Chrmoe thingy....

And please use a more descriptive title next time. "effect help" doesn't really let us know what it is you need.

Okay, Mr. "not too hard"

Perhaps a few hints on how you made the chrome effect in that image?

I'll do the tutorial for you, if you give me enough info to make a go of it...

Hints
Base image is with 3 colors (black, white, blue.)
Tile reflection.
Glass blocks.

Heres what I came up with.

A bit less blue I would say, just a bit.
Other then that, you are all set
