program for creating game background help

[Vercingetorix]

Hi, i was  just curious is there is a way to get a program like Photoshop or Graphics Gale (free edition) to display a repeated preview of the tile your working on as your editing it? I was playing around in graphics gale on  a 32x32 pixel background tile and loooking at the preview set to actual size i couldn't help wondering if there was someway i could get it to dispay what i'm working on tiled along all that empty space? if there isn't any way to get it to display like this are there any freeware programs out there that can do this because it would be of great help to me?

any assistance is appreciated
thanks

Cosmigo Promotion has a very nice tilemap mode where all tiles which are the same get updated when you draw on one of them.
I am not sure if this is in the free demo version tho.

If you just want a single tile which tiles with itself there is also tile drawing repetition under the lock grid settings, which should be in the free demo.
