That is not possible on mobile devices, only on PCs with the 2nd button in the upper right corner of your browser. You have to set the size by hand, by dragging the window borders. If you have set the window to the correct size, you can toggle between that window and a full screen window with the two buttons in the upper right corner.
AFAIK, there is no skin that offers that option. Some skins will open some things in a new tab or window, like a map or a web location (i.e., a thumbnail that links to another site outside of the album itself). And many skins open images in modal windows (lightboxes), but that's not the same thing.
Forcing a link to open in a new tab is generally discouraged in modern web design. The site visitor can cause that to happen by right-clicking a link, but it should be under the control of the visitor, not the site designer.
