Yep. It might look scary but is actually very simple if you just want a straightforward text. Just pick the style of text you want, type it onto a transparent background, check the size, save as png.
You can get more ambitious with gradients, glows, additional pictures with the text etc, but it’s not necessary. There was a basic tute on it somewhere on the forums ages ago. If I can find it I’ll link it but that’s the gist of it.
This is probably far more that you’ll ever need to know about headers (I’d forgotten how much detail it went into for options), but here it is if you ever want to get more ambitious.
