SOURCES creation and modif / low def picture(s) can be added
It must be possible to add low defs picture(s) to SOURCES. SOURCES can be linked to OPE, CONTEXT, FINDS and TREATMENTS.
Accordingly to "Base Joconde" french référence ([[http://www.culture.gouv.fr/documentation/joconde/fr/partenaires/AIDEMUSEES/normes-image.htm]]) the following limits can be acceptable :
resolution : 72 dpi
mode : RGB
file type : .jpg (but we can think later of a SVG support for drawings)
file size : less than 150 ko
picture size : 640x480 minimum, 800x600 maximum
Theses pictures must be provided as thumbnails in the correct sheet (OPE, CONTEXT, FINDS or TREATMENTS) with possibility to show the complete image.
