ARTstor has very recently added the capability to save an image detail to an already existing image group. Remember that you must have created an ARTstor account in order to create image groups.
To create and save a detail, double-click on an image thumbnail. This brings up a window with the full image. Use the cursor to mark a box around the portion of the image you want as a detail. Once the detail has fully loaded, click the icon at the lower right of the window that looks like a box with dots in it (it’s adjacent to the thumbnail). You will then be prompted to choose an image group to which the detail will be saved. Click Save or Save & Open, and you have the detail saved in your group.
