To resize an image, modify an image reference that normally looks like:

      [image:26987]

to something like this:

       [image:26987@64x48]

where 64 indicates the width in pixels and 48 is the number of pixels in height.

If you have a block of text, where you want the spacing, such as line breaks or columns, to be preserved, start and end the block of text with three equals signs. The text will be displayed with a fixed-width font.

If you want to make sure that no other formatting is applied in the preformatted block (e.g. bold, italics, links), start and end the block with six equals signs instead.
