Is this possible in adobe Photoshop 6.0?
Adobe did not add the "text on a path tool" until Vesion CS. Any version prior to that would require warping the text.
ADOBE PHOTOSHOP 6.0
Warping type layers
Warping allows you to distort type to conform to a
variety of shapes; for example, you can warp type
in the shape of an arc or a wave. The warp style you
select is an attribute of the type layer—you can
change a layer’s warp style at any time to change
the overall shape of the warp. Warping options
give you precise control over the orientation and
perspective of the warp effect
Warping applies to all characters on a type layer—
you cannot warp selected characters. While
warping is applied to a type layer, you cannot
resize or transform the bounding box for
paragraph type.
Note: You cannot warp type layers that include Faux
Bold formatting or use fonts that do not include
outline data (such as bitmap fonts).
To warp type:
1 Select a type layer.
2 Do one of the following:
• Select the type tool ( ), and click the Warp
button ( ) in the options bar.
• Choose Layer > Type > Warp Text.
3 Choose a warp style from the Style pop-up
menu.
4 Select the orientation of the warp effect—
Horizontal or Vertical.
5 If desired, specify values for additional
warping options:
• Bend to specify how much warp is applied to
the layer.
• Horizontal Distortion and Vertical Distortion to
apply perspective to the warp.
6 Click OK.
