A decorative image raises the value of an object by adding another material to the base item. Decorations have quality levels. The base value of a decoration is 10☼, multiplied by its material multiplier and quality multiplier that are separate from the item itself.
Adding decorations to an item does not increase its weight.
When an item is decorated, it is shown with double angle brackets - for example, a (no quality) decorated +steel battle axe+ becomes a «+steel battle axe+». Decoration quality is shown outside the double angle-brackets, the item quality remains within them with the item. So if you have *«+steel battle axe+»*, you have a +steel battle axe+ with *decorations* on it. When an item has more than one decoration the quality level of the best one is shown. Decorations do not affect combat multipliers.
You cannot stud a metal object with the type of metal it is made out of. For example, you could not stud a Rose Gold statue with Rose Gold.
You cannot specify a specific object for a dwarf to decorate. Dwarves will use the closest suitable object. The exception is when encrusting something with gems, where you are able to specify a category of goods to be decorated. Of course you can always seal in (forbidden doors) your artisan Rumpelstiltskin style, complete with workshop, the materials you want him to use and the objects you want decorated (dumping them inside the to-be-sealed-off area might work best) to ensure proper conduct.

 Tips and tricks
If your fortress is above ground or you otherwise have inadequate natural rock walls to engrave, ropes or bags sewn with images can be a way of recording your fortress' history instead of stone detailing. When built as restraints (for decorated ropes), or as containers (for decorated bags), dwarves can gain happy thoughts by admiring them, so they can function as makeshift tapestries.
