[[JOSMImage(mapmode/adjustimg,48,link,middle,margin-right=20)]]

Accessible from:
* [wikitr:/Help/Menu/Imagery Imagery menu] as ''**New offset**'' item. 
* [[JOSMImage(dialogs/layerlist)]] [wikitr:/Help/Dialog/LayerList Layers list] panel's [wikitr:/Help/Menu/ImageryContextMenu context menu] of imagery layers.

JOSM switches into an own mode with a hand below the mouse arrow. Instead of objects the selected imagery is moved by dragging or arrow keys. Alternatively, entering the offset as two real numbers (ℝ) separated by semicolon (`;`) is possible

In order to save the offset as bookmark a name has to be entered.

Once the offset is set it is indicated in the layer list panel and bookmarks are displayed below the entry ''new offset'' in both menus.
