Details, Details

To post pictures here, you would need to host them somewhere else (unless you have a paid account, in which case you get space to upload photos on lj's servers), like Photobucket or Flickr (both have decent free account options) and then either post links to the pictures, or display the images themselves (the HTML tag for that is [img src="www.address_of_picture_goes_here.com"] where [ ] are replaced with < >. If it's a lot of pictures, you probably wanna put 'em under the LJ cut tag.
