According to Google's help pages, one can embed pictures from Google Photos onto an external web site:... but, although it says there's a Link to this album on the right hand side, with an Embed Slideshow, I can't find it anywhere.There's nothing about embedding under Share, or anywhere else.How do I embed an album of photos uploaded to Google on my web site?
How do I embed a Google Photos album into a web site?
google plus;google plus photos
Proposed by an anonymous user, as a suggested edit to the accepted answer:Setting up Albums and generating the code to embed them in a web site is made unnecessarily complicated by Google.  They really should make this more intuitive.  Below are detailed instructions for how I learned (the hard way) to do it.CREATE A NEW ALBUM IN GOOGLE+ PHOTOSIn Google, select the icon at the upper right that looks like a tic-tac-toe board (or waffle iron), and select the red Google+ icon (may have to sign in).Open the drop list on the upper left that says Home, and selectPhotos.Select All Photos from the top.To see any existing Albums, select More at the top, and then Albums.If no photos are loaded, you will need to load some before you cancreate Albums.Go back to All Photos.Upload some photos by selecting Upload Photos, and following thedirections.When some photos are uploaded, go back to All Photos to see them.Click on an individual photo, and a bigger view of that photo willpop up.Move the mouse to hover over the big photo, and a circled check markwill appear in the upper left corner.Click on the circled check mark, and options will appear in a bluestrip across the top. Select Copy.A pop up will appear with the existing Albums, or you can enter thename of a new Album to create one.When done, hit Copy at the bottom.EMBED AN ALBUM IN THE WEB SITE (Weebly as an example)To create the links in the site requires the set up of Albums first in Google+ Photos (see instructions above for that), and then you have to go to the site called https://picasaweb.google.com to get the embedding code.Go to the picasaweb site.Any Albums that have been set up should show up under the Home tab.Under the thumbnail for each Album are three lines: the Album name, adate, and the number of photos.Just to the left of the number of photos is a little icon that iseither a padlock or a roundish gray-and-white icon that is hard todescribe.If it is a padlock, it means that the Album can not be seen with alink, and you can't generate embedding code for it, so it must bechanged.To change it for linking, click on the Album, select Actions, andselect Album Properties.In the Edit Album Information pop up, open the Visibility drop listat the bottom, and pick Limited, Anyone With The Link, then SaveChanges at the bottom.Then select the Home tab, and make sure the icon under the Album haschanged.If it is the right icon, then click on the Album, and on the rightside, click on the the blue text that says Link To This Album.Then click on the blue text on the lower right that says EmbedSlideshow.A pop up will open, and select the slideshow size that is desired(large is the one I pick).Then copy the code in the yellow box, and paste that into a WeeblyCustom HTML code box.Hit Done on the pop up.It is also a good idea to then copy the link address that is on theright under Paste Link In Email or IM, and then paste that in aregular Weebly text box.After putting it in the text box, you will have to highlight thattext, and select the option Weebly gives to make it a hot link.The reason why it is a good idea to paste this link in along with theembedding is that the embedded slideshow may not show up on somedevices (mostly Apple devices), and the link gives those users analternative way to get to the photos.To size the embedded slideshow, edit the code to include height andwidth (e.g. 500 and 700). Then publish the Weebly site, and checkthat it all works.
