Yes and no. The current (what you refer to first) window will close only
if the url is different.
If same url, then the window is brought up back on top, is focus()-ed,
which is efficient use of the user's system resources.
Still several considerations favor slideshows over that script:
1- Mozilla 1.x, Firefox 1.x, Opera 7+ have an user preference to disable
focus() command. So, (workaround) your page must indicate to set Allow
scripts to: Raise or lower windows checkbox to checked
2- Your page *must clearly and explicitly indicate* that only 1
secondary window is opened and then recycled, reused for the photo album
gallery when he does a normal left click on thumbnails. The user can
always open any enlarged image in a distinct, separate window by doing
right-click and then choosing open in a new window or even open in a new
tab. So the script is flexible, user-friendly and also
javascript-support independent.
3- Slideshows can use rel="prefetch" feature which then would/will be
most likely faster (more user resources friendly, efficient) than
opening a secondary window.
4- The script can not overcome special user setting/theme/preference
like width of scrollbars: this is already mentioned in the script comments.
5- If the url is different but the image size are the same, then the
window should not close and be re-created; it should load the new image
in the current window. The script currently does not do that: I just
realized this today.
If I were you, I'd look for S5 slideshow:

Usable/Accessible)

I would not do that. Otherwise you make your text less accessible, less
interoperable (think of people who would copy-N-paste your text, or save
such text, others who would want their browser to submit such text to a
translating feature or site, etc.)

You can watermark your name with IrfanView along with some copyright
notice in your image: that's good and ok.
An excellent example showing perfectly what I have in mind:

Ok. No problem.

Good question (I do not get this question asked enough/often). Yes, it's
free. Just mention my webpage and my name as contribution and author at
the beginning of the script.
