The first picture I posted from my Ipad of my Spiderweb blocks worked perfectly following Sandygirl's instructions. It was so easy and quick. I can't get it to work again doing the exact same thing. Will it work in the future? The instructions were: go to post new thread,type in the title, click on the little paper clip (manage attachments), choose a photo from existing, click on upload, close window and that was it. It appeared into the box and I typed in my words and posted it.
