Here’s a quick set of instructions. If you’d like a remote session we can do that too.
Go to the wordpress dashboard. Click on “FooGallery” on the left side.
You’ll see a list of image galleries. The one you want is “Sponsors Gallery – home page”. Click on that. You’ll see a horizontal list of images
Click on “Add Media” – blue button to the lower right of the images. Or you can click on that “+” sign to the right of the images.
This will bring you to the add media to gallery page. From here you can upload an image using “Upload Files”
Upload your image, and then you will be returned to the gallery page; and then from the gallery page, click the blue Update button on the right side
and the image should show up in the sponsors galleries on all pages
