4.2 Points to Remember when inserting Alternative Text

Make your description meaningful. A numerical file name for a picture is unhelpful.
If available, give the data from which a chart or graph is based. If not summarise the results.
Do not include “Picture of” or “Chart of” in your description. Screen-reading software will recognise what type of non-text element is present.
Text in shapes can be copied and pasted into the Alt Text Dialogue Box. In Word 2007 this process will be done automatically
If the file name of a picture has been inserted automatically (Word 2007), delete the file suffix, e.g. .jpeg. You may also want to make the text more meaningful.
If the non-text element is purely decorative you can force screen-reading software to ignore it by entering “” in the Alt Text Dialogue Box.
