All requests except for image tables were worked into the v1.3 release. The following are linker tables for the eimage table. But there may be a different solution for files/images in general.

• contact_image (maybe should be image_contact) (v1.4)
• feature_image (maybe should be image_feature) (v1.4)
• stock_image (maybe should be image_stock) (v1.4)
• organism_image (v1.4)

Property Tables

• eimageprop

(v1.4) (VG added: for DDL, see request #3)
