WordPress galleries are a good way of displaying photographs and provided that your original photographs are of good quality, you should see good clear images on the screen.
If you are using the Block Editor (default) you can refer to this description for adding a gallery in Easy WP Guide. If you are using the Classic Editor, the way to add a gallery is first to Insert Media and then from the media screen to Create New Gallery.
There are a couple of things to note.
Viewing Full Size Images
A gallery will normally show an array of small images and you can click on any one image to view the full size version. To make this full size view happen you need to change the Link To setting to Media File.
Members Portrait Gallery
If you want to show a set of headshots of the committee members, a gallery is a good way to lay these out. However it doesn’t work well in the block editor if the number of images is not a multiple of the number of columns. For example if you have seven committee members and you’re showing three columns, you’ll get two rows of three and a single photo on the last row.
With the block editor, every row is made the same size and the photo size is adjusted to fit, so that last single photo will appear three times as big as the others. This works quite well with photographs from an outing, but not for headshots.
In order to prevent this last row from being automatically resized you need to use the Advanced settings to add an Additional CSS class as shown below.
One annoying feature of the image uploader is that they sometimes get rotated for no apparent reason. I haven’t found a way to stop this happening, but you can fix it after the image has been uploaded.
In the Media library, click on the image that you need to fix. Underneath you should see an Edit Image button. Click that and you go to the Editor page.
The second and third buttons above the image allow you to rotate left and right respectively. The fourth and fifth buttons are for mirroring and the first is to select a specific area of the image, but you shouldn’t need those.
When you have corrected the orientation, just click the Save button.« The Media Library Home Menus and Links »
