So if I create a Gallery Link (50th Reunion Photos)on the left & then create New Photo Gallerys for each of the major events of our reunion. Can classmates upload their snapshots to sub-galleries and can an admin approve them before they are visible to logged-in classmates?

Joan,

Yes, all of those options are available when you create the photo gallery. You can choose "Admin Only, or Classmate Upload, or Classmate Upload with Approval"

Just EDIT your gallery from the Gallery Creator and search for this section and drop-down menu:

Upload Permissions:    
Only Admins: Allows only Site Administrators to upload photos to the gallery.
All Senators: Allows both Site Administrators and Senators to participate in uploading photos to the gallery. Each Senator can create his or her own unique gallery within the master gallery. All photos uploaded by Senators will be credited to them!
All Senators, But Approve Photos First: Allows both Site Administrators and Senators to upload photos, but before photos added by Senators go live on the site they must be approved by an Administrator first.

Kyle, I dont find the option... "Just EDIT your gallery from the Gallery Creator and search for this section and drop-down menu" where else might it be?

He means select EDIT in your gallery for the page within that gallery.

So after Edit Site Page, EDIT the gallery. After that the top heading will say "Photo Gallery Creator" and then you have your galleries. Click the EDIT option for any page within that (has Photo option also) and then it has the options Kyle listed.

I agree it gets a little confusing at first, but ends up being simple

Kyle,
On a related subject, how can we prevent photos from being copied off of our site? I'd like to prevent the ability for people to right-click on an image and save it to their system.

There is no way to prevent copying the image.

If you prevent right-clicking, there is still the PRINT PAGE AS PDF, then copying the page from the PDF.

There is also the CTRL-PRTSCN which copies the page to the copy-buffer, where the picture can be pasted into any paint program and edited/saved.

And there's

1. Firefox media tool breaks up the images on a page for easy saving
2. Firebug which digs right in and gets the raw link.

All right-click code does is annoy users

Mark,

The fundamental problem with trying to prevent people from copying images you put onto a website is that in order for users to view a webpage or any component thereof, their computer has to have already copied that data. Any moderately sophisticated user can fairly easily circumvent pretty much anything you can do to restrict copying of an image you've posted for public viewing.

Traditional ways of dealing with this include: watermarking an image to make its re-use obvious and undesireable; making only a low-resolution version of the image available online (making reuse undesireable); or otherwise altering the image prior to display . In all these cases, the result is the image you display on your site suffers the same indignity that any attempted copy would.

Other methods which use technology to interfere with the usual interfaces or web browsers typically just annoy users, as Jack said, and also typically do not prevent sophisticated users from copying the image as you present it.

The last ditch method is to use the law to threaten and beat potential copiers into submission. The cost/benefit analysis of this method does not indicate any value for content producers too small to purchase the cooperation of legislators and/or law enforcement agencies.
