Vids you need to upload to Youtube then post the link here.

Photos you can upload using the go advanced button below the reply box, go to manage attachments & a pop up window will allow you to select & upload.
You can then use the little paper clip icon to add your picture to the post or just leave it to appear as a thumbnail in the post.
Alternatively upload photos to somewhere like Photobucket & post the link here.
You may need to resize your photos before uploading.
