Exported maps is without images.

Probably bug in images export. Tiff should be exported as PNG in /data folder, but no PNG there...

Any messages in the qgis2web log?

Would you mind adding this information to #148? It's the same issue - different GDAL versions needing different param lists.

@kelv-cz #148 seems now to be fixed, so it would be great to hear whether it has solved the bug for you as well.
