background texture/tiling

Is there an easy way to tile a imported picture or apply it as a texture to form a map background. I've created a grassy map the only way I found by copy and pasting a lot but searching here it looks like it might have previously been a feature, talk of yellow and green dots but i can't find them or i'm just being thick. Really just want to find if theres an easy way of doing this rather than scaling a picture and in this case ending up with 200m long bades of grass.

The easiest way to make a grassy map is to take your tile and use an outside program like GIMP or such to make it then drop and drag it in to roll20. Someone else will probably post another way but that is how I do my maps.

thanks was hoping there might be a better way but look like gimp it is

Yeah, dungeons could be drawn very easily using dynamic lighting and fog of war if we could use a texture as the background.
