Realistic Textures

Is there a Photoshop function to make a digital photograph tile, so that high-rez images of things like rocks, water, and metal can be used in low poly games?

- Dividing your image into two, swapping these halves over, flatten, blend the seam, and then repeating on the opposite axis to achieve a seamless texture. Preferred option, and then tile or use UV mapping in your modelling package.

- Define a pattern (EDIT menu), and then fill a page (EDIT menu). Not advisable as you have seams, and in the end create a large image which will hamper your rendering.

Well that is definatly a differant way of doing it, not good, not bad....just differant.
