is it in the dining or living and can you put frames within it?
Answers: within those rooms, you can also situate them within a corner which looks good. It softens the straight lines of the corner. I'd avoid putting frames or pics contained by a curio cabinet. Usually they're too large for the nouns, and ofver-shadow any of the beautiful pieces of cup, crystal, metal or other shiny items.
good luck
You can put contained by whatever room you want, depending on what you craving to display. It's YOUR home! Frames would be a nice addition beside other items, but not sure I'd go next to them exclusively.
