Drawing a line, arrow and arrowhead in Photoshop CS6

I can't figure out how to edit the arrowheads after I've drawn the arrow with the line tool. The only way to get the new dimentions to apply is to draw a completely new shape?

Only one problem I have the photography plan and the rest of the presets don't seem to be available. trees, boats, flowers but when I try to add more it takes me to explorer (file manager) and shows me an empty folder... So I'm stuck with a giant headed arrow or nothing...

Yet another option is to draw an arrow and save it as a custom shape from the Edit menu. It will appear in the Shape dropdown as shown in Trevor's screen shot. You can use it to draw a Shape, Path, or Pixels, depending on what you select in the Options bar.

Another option wort remembering are the custom shapes.

I can't remember if the arrows are in the default collection, and I usually have mine set to All

Yep. There you go. The Arrows have their own set, but like I say, I can't really think of any down side of having them all loaded, unless your system is very short of RAM.

Hi Denson:

1. Select the Line tool
2. Select the Shape mode
3. Pick your fill and stroke colors
4. Click the gear to add the arrowhead to the start or end of the line (or both)
5. Set the Height
6. Hold the Shift key and drag your mouse to add a straight line.
