Effect of UV curves tool not rendered

When I adjust the colours of a texture with the curves tool I see the results in UV window but it does not render. Can someone please point me to what I’m supposed to do to get the desired result?

PS. I’m using 2.47


After using the curvestool, you should save the changes to the image in the UV window and then reload the image.(You can check this, using the textured Drawtype in the 3Dview)
In the material buttons window, you can either activate the texface button, to show the image assigned via UVeditor, or assign the image you’ve saved via the texture panel, to show up at render.


Thanks for replying. This seems a bit awkward though. I discovered its easier to use the node editor.
