I don't have any pics but if your lookin for ideas:
I have an old hat stand which on which I have my akubra, a western stirrup and my show bridle.
I have an old rocking horse which acted as a saddle stand when I borrowed a friends expensive saddle ( I didn't want birds to poo on it in the shed) theres also a girth on itm at the moment
I've run out of room on the walls for posters so I put them on my cupboards. I also have a ribbon hanger thingo on the door of one of my cupboards.
My helmet hangs on the door handle
That's about it for now but there are more ideas on this webpage: Horsewyse Magazine–Turn Your Bedroom Into a Stable
Have fun :)
