Topic awaiting preservation: how to tile an image for the background of a larger image?

okay, i know i used to do this in photoshop 4 .. but it has been so long i have forgotten how and after searching online i have not turned up anything ...

if i have a smaller image that has a pattern in it that i want to tile into the background of a larger image ... what step (s) do i need in order to achieve this?

Flea: To tile an image, I use the stamp tool and offset my image to avoid a side effect. Repeat that several times and voilà. To avoid a bit the repeating effect, you can also do the same thing on a highpass version of your picture that you set in overlay or hardlight at ~10% above your tiling image.

Hope that helps,

Ctrl + A to select the entire background image.

Edit > Define Pattern

Go to your large image and fill the background with the pattern you just defined.

ah yes, that is what i was trying to remember thank you!

To make it tile seamlessly, offset the tile by 50% of the tiles size in both directions and blend (clone, smuge, liquify..) the seams the offset produces.
Then fill with it.
