drawing a sprite to an image

[WSPSNIPER]

i want to draw a sprite on to an image so i can draw a bunch of sprites then display the image

i tried sprite.draw( image )

here i was drawing to an image i created, im doing this because im putting tiles on the entire map with 2 for loops and every frame it needs to redraw the tiles so i wanted to put them to an image ( maby another sprite ) and draw the image every loop hopfully speeding it up a little

i was looking at the doc and could not find anything so if anyone could give me a tip it would be cool

It's possible with the RenderImage class, available in SFML 2.
