At the moment Google Slides only allow you to add 1 image at a time, which can be very tedious if you would like to make a slideshow presentation with a few dozen images. However, there is a workaround if you have PowerPoint or Libre Office (Free).
· In PowerPoint Create a New Blank Presentation.
· Go to Insert - Photo Album
· Insert all images, you can also correct the sequence of the images if they are out of order.
· Once complete, save the PPT.
· Open Google Slides Website
· Go to File - Open - Upload – Select the PPT you just saved
· Once Uploaded, you will have your slideshow ready.
· You can save/share it or you can further modify it as per your liking.
If you don't have Powerpoint, you can also create a Google Slides file using Libre Office (free) in a similar way.
Google Slides from Libre Office Presentation
Install the latest version of Libre Office on your computer: 64 bit or 32 bit (250 Mb .MSI installation) from http://www.documentfoundation.org/
In Libre Office, create a new Impress presentation.
Browse image files on your computer and select multiple images (using Click + Ctrl or Shift keys). Click the Open button to add them to the list of files: here you can preview them, arrange the sequence, pick the number of images per slide, include a caption area and select to maintain the aspect ratio.
Select Insert Slides: a new slide is created for each image.
In Google Drive, sign in and select New…Google Slides
Select the file. This will convert it to Google Slides format with the same number of slides.
Thanks to for informing about Libre Office.

I used this blog and it worked like a charm! I was able to create a google slide show with over 70 photos as a single all at once process. Key was that each photo was named in such a way that they fell in the correct order. The first image is Pg 1.jpg, the second is Pg 2.jpg. That way when you import all of them into the PowerPoint project it will line up in the sequence you want. I also had to limit the entire size to about 150 mb or it doesn't work on Google Slides. I did this in Photoshop by creating a folder of the same photos but as smaller file sizes than the originals (which were 300 dpi scans--big files), by changing the copy image resolution to 100. Remember, since it was going to be viewable on a monitor or iPad, or even phone, the higher resolution was unnecessary but keeping the file size small was necessary. Thank you all!
