Advice needed for purchase I made

Hello, I have already talked to two different board members about this but I thought I would put it up on the board. I purchased a cabinet card photo from a fellow board member a week ago through paypal. The board member said the would pack up the photo and mail it out over the weekend. I still have gotten no word from the seller and I sent a email to them yesterday and today and still no response. I even saw they were online on the board earlier today and shot them a message using this website's message system. If I had just spent thirty dollars on the item I would not worry about it but I spent a lot of money on the item and want to know what is going on. I mean it is okay if there is a reason for delay in mailing the item but all someone has to do is tell me. Anyway, I know this is going to make me look like the bad guy and that I am over reacting but it has been over a week since I sent payment with no response or timetable for when the item will be shipped. I guess by the end of the day thrusday I am going to have to file a request for the return of my money with paypal. I don't want to do that because I want the photo but, I don't know what else to do because I do not want to just lose the money. I know I might be over reacting and I am still just a college student and young to the pre-war collecting game but I don't see any other option. Thoughts would be appreciated
