Hi Lars,

To convert the image to png and include the image using HTML.

LON-CAPA converts gif/jpg/png to eps, it currently duesn't support the
other direction.

The suggested mechanism is to do something like:

1) Use the <img> tag
  <img src="somfile.png" />
This will both view and print properly. You can include tex sizing
  infomation by doing
<img src="somefile.pmng" TeXwidth="30" TeXheight="40" />

The 30 and 40 are assumed to be mm

If the .eps version doesn't exist LON-CAPA will convert the png to eps
on demand.

2) Use <web> and <tex> tags
  <img src="somefile.png" />

Here you will need to have created/published both the png and eps
images. Also make sure that you have a good valid <allow> at the
bottom, this will make sure both the eps and the png get replicated
and will print properly.
