All pictures and graphics must be floats to allow the different transformation formats to deal with them in the way they require. Always include “!p” in the float command to ensure that there is enough freedom in the placement. Ideally “h” should be included to minimise the number of diagrams that are not in situ, inclusion of “t” and “b” where possible will give the maximum amount of flexibility.
For transformed formats aimed at screenreader use all images require an “alt tag” containing a full text description of the diagram. Not all transformed formats can be provided with this information but commands have been created in the configuration files for those that can in order to make use of the information. Examples are given in the subsequent sections.
