Align Selected Graphics...
Align Selected Graphics makes selected graphics cells line up with the first graphic in the selection.
In the dialog box, specify which edges of the graphics (left, right, top, or bottom) you want aligned. Specified edges are aligned with those of the first selected graphics cell.
When left and right are specified, all graphics are set to the same width. When top and bottom are specified, all graphics are made the same height. When all four edges are specified, all graphics are made the same size.
This command is useful for aligning animated graphics.
This command sets the options ImageSize and ImageMargins on the selected cell objects.
