KK, to save an image on the web, tap it and select "save image" - that will place it in your camera roll, if you try to use the 'choose file' option to attach it it will crash the browser, so you have to host the image somewhere and link an embedded version, eg I grabbed this image off another page, saved it, uploaded it to Smugmug, my photogallery and shared it by selecting the embeddable forum version. Then copied to this page,
YouTube embed, open YouTube app, find video, click on share button, copy to message and then copy link, click on video embed button here and paste in copied link. (Of course you can't see it on the iPad because YT still uses lame flash instead of proper html5!
