Instructions for how to upload multiple photos to your WordPress website and then create a photo gallery page or post.
Go to your Dashboard, scroll down to Media, and select Add New.
If you using a Mac:
Select the files in Finder by holding down the shift key and clicking on the photos you wish to upload to WordPress.
Drag the images into WordPress New Media Drop files here (see below).
Or, if the images you want to add are on your Mac desktop, you can drag them to Drop files here.
If you are using Windows:
Instead of dropping files, as noted above, click on the Select Files button
After clicking the Select Files button, navigate within Windows to the folder that contains the images you want to upload. Hold down the shift key to select multiple files. Then click Open to complete upload. (This might be different in Windows 10, which I have not installed yet).
Later you should edit the image Alt tags, which is important for screen readers (accessibility), as well as SEO.
How to Make an Image Gallery:
If you want to make a gallery of your images, go to the Page or Post which will contain the gallery and click on the Add Media Button. This will bring up all the images in your Media Library.
Click on Create Gallery
Select all the photos you want, then click on Create a new gallery
The next screen will allow you to drag and drop to reorder media files. Under Gallery Settings you can choose the number of columns, size, random order, and type of layout.
Next click on Insert Gallery. Check to see if you like how this looks on the page by clicking on Preview Changes. When you are finished creating your gallery, click publish (or update if this is a previously created page as below).
