How to answer/ask questions?

So this may sound silly, but I have a lot of questions like: “Where is this dress from?”, “Where can I find that chair?”, “What fabric is on that pillow?”, and this may be my lack of tumblr savvy, but unless you are a little more specific is there someway I can tell what picture the question was posted from? I don’t want you all to think I’m ignoring any questions, but I just don’t know what people are referring to! So if someone knows how to figure this out, let me know!
