how much quality does she require? how much is her budget?
taking pictures of paintings is tricky. there is problems of lens distortions and perspectives. and then there is problems of lightings, white balances. and then there is a big problem of color management.
i think the best combo wouldd be a D-SLR camera with a tilt/shift lens. these lenses don't suffer from perspective distortions if you know what i mean. but they are about $900-$1,000 a lens, no matter if they are from Nikon or CAnon or any other lens makers. they're also manual focus.
this combo is actually very good if it is true that your sister is not handy with things that have many buttons. you just set the whole thing up for her: the lightings and the camera settings, then all she'll have to do is: focus, and press the shutter button. by the way, NEVER use the cameras' popup flash.
if the budget doesn't allow that setup, then try to get the best lightings you can, and use any good PnS cameara. seriously, something like, a Sony V3 will do a very great job. just set it to P mode, turn off the flash option, and put it on a tripod. all she have to do is making sure the camera's lens is leveled with the painting she's taking, to reduce as much distortions as possible. that is, position it so that, the center of the lens looks directly at the center of the painting, perpendicularly.
P/S: i assume you'll set the camera's settings right for better color reproduction. like setting white balance and/or color space.
