Why does the figure show black image only in Matlab?

My sidebar image on Tumblr won't show up?

• For the past few hours, I've been trying to figure this out. For some reason, I CANNOT get the sidebar image on my Tumblr blog to show up. I've tried clearing, and then re-uploading it numerous times, and nothing is working. I've tried asking the theme maker, but she still has yet to answer. Yeah sure, she's logged on, but bothered answering my question? No, she hasn't. Quite an irresponsible theme maker, if you ask me. But anyway, I'm just getting really frustrated, because without a sidebar image, it makes my blog look weird. Is anyone else having this problem, or is it just me? (By the way, I don't know if this is just the people who run Tumblr ******* up again, or what.)

• Answer:

  is there a button that says show photo or sidebar image/photo if so then click it , if u already have done it then wait a few minutes because it does take a few minutes for it to show, if all this fails either try messaging the theme creator again or change your theme
