this is not generally true. It depends on how the wood was treated and whether it is real wood or just pressed from wood shavings. The glue of the latter contains formaldehyd, which ist not only harmful to your prints.
Wooden frames are usually thicker than metal frames. it depends once more on your taste and the style of your pictures. Regard the frame as part of your artwork.
