Image support

[marcel-kehrer]

Currently it is not possible to insert images into cells.
If you try to import and save a file with images, they are simply deleted.

Hi,
It is mentioned in the readme and FAQ: "What You Can Write Is What You Can Read". Everything else is discarded.
The library is meant as a writer/reader (exporter/importer) and not an editor.
The main purpose is to write or read data - especially machine readable - using spreadsheets.
There are currently no plans to add embedded data into spreadsheets, sorry.
For that extended purpose, there are probably much more powerful libraries available.
