Why not, it may well, carefully read the wiki and then you will
understand which module you need to add to "uses"

I'm afraid, it can't... I remember that writing images already was
unnecessarily complicated and lost motivation to restart with reading.

I have writen "uses xlsxooxml", but No image can be accessed.
In xlsxooxml.pas, there is a methord  named "WriteMedia" in
TsSpreadOOXMLWriter, but, No corresponding "ReadMedia" in
TsSpreadOOXMLReader.

Excel OOXML = Writing only
OpenDocument = Working (+++)

(+++) Only very basic image support: no transformations, no cropping,
no image manipulation.

oh, it is Writing only in OOXML, thx.
I wish it can read image in the future.

Added a basic image reader to the XLSX format (far from complete).
