These pictures are logically glued together and described in the atlas source text prepared using the TeX/LaTeX typesetting system. LaTeX2HTML converter is used to produce the actual hypermedia document, while the same source can be used to obtain a more classical printed version of the atlas. The static character of the HTML hypertext document is made dynamic through JavaScript functions, which add the required interactivity. Results: The atlas is accessible using standard JavaScript enabled Web browsers. There is always one main window with the text, table of content, index, active section headers and other hypertext links, and links to individual images. All the images are displayed in separate windows. The 900*900 pixels images are used as standard resolution pictures, the higher resolution images (2000*2000) are displayed on demand in a separated ``magnifying glass'' window. This interface can be used to compare several pictures displaying them in the same time and providing also a tool to focus on the most important parts of the large windows. Use of the higher resolution images leads to no information loss through this process. The interface could mimic the fine focusing of the microscope that provided the picture and is a series of images taken in consecutive planes of focus. Discussion: The atlas was primary produced as a stand-alone package, stored on local disc or CD-ROM. In this form it is suitable for pre-graduate and initial postgraduate education. Currently, it is being converted into very flexible, easily available and expandable diagnostic tool available through Internet. The Internet accessible atlas may be easily updated and expanded with new images and text. Images at different compression levels could be stored, the low resolution one used to fast scan and the highest resolution images used for detailed comparison with unknown specimen. Through the very high speed network (e.g. TEN-155) it will be possible to transfer even the raw data images with resolution above3000*3000 pixels.
