Activate the macro mode

Instead of shutter priority "Tv" mode, try setting to program "P" mode instead. Also, turn off the flash, and set to macro if shooting close-in (press downward on the little flower icon on the back disk). If pictures come out blurry, try using a tripod to hold the camera steady, or set the camera down on an object so it doesn't move while taking the shot. Try using the timer to activate the shutter to allow the camera to remain even steadier for the shot.

I don't know how close you need to be to the paintings, but if it's close enough to need the "macro"setting, then you need to activate it for close focussing.

To activate macro mode on s5000 you need to press the 4-way controller on the back of the camera to the left (it's labelled with a "flower" symbol).
Make sure you turn macro mode off once you've finished with it as it will cause autofocus to slow down with non-macro focusing.
Good luck,

You've got an excellent camera, very capable of doing such. Would also recommend setting it to portrait mode, turning off the flash, selecting macro, and ensuring that you have plenty of good "diffuse" lighting. Most important of all, recommend using a tripod and taking the pictures using the camera's timer to activate the shutter. This will prevent camera shake as the shutter is activated allowing much sharper pictures.

Now, just in case, here's your camera's user manual as it also has great pointers for taking macro pictures.
