Word, at least to me, is synonymous with Microsoft Word these days. But you seem to be saying you have already saved it as a word document. So you don't mean MS Word then ?
I suspect someone will automatically know what type of document you mean but I'm afraid I'm being a bit thick again.
Probably best to wait until that person comes along, although in the meanwhile I can say it may be worth searching the Net for an freeware application that can convert from one format to another ?
Alternatively, if you can copy and get the picture into your PC's paste buffer somehow then maybe you can save it in a different format, one that tinypic likes ?
