The usual way to add multiple photos to the Windows 10 desktop as wallpaper is to select the Slideshow option, which this Tech Junkie guide told you about. The slideshow displays each picture separately. However, you can also combine, or merge, multiple images into single wallpaper by setting up photo collages. Then you can include your favorite photographs in one desktop wallpaper instead of a slideshow.
Setting Up Photo Collages with Picasa 3.9
Google Picasa is photo-cataloguing software that has extra options for editing images and setting up picture collages. It’s freeware you can add to various platforms, including Windows 10, from this page by clicking the Download Picasa button. Then open its setup to add this program to your software library and launch its window in the snapshot directly below.
Next, choose a few images to include in the slideshow by holding the Ctrl key and selecting them with the mouse. Then click Create > Picture Collage to open the tab shown in the shot directly below. That shows you a preview of the collage on the right and includes the options and settings for them on the left.
Click the drop-down menu at the top of the Settings tab to open a list of collages you can set up with Picasa. The software includes Picture Pile, Mosaic, Frame Mosaic, Grid and Contact Sheet collages to combine your photos with. To set up a collage that automatically fits images on the page, select Mosaic from the drop-down menu.
The Mosaic collage is quick to set up as it neatly arranges the photos as shown directly below. You can move the images on the grid by dragging and dropping them. Drag the Grid Spacing bar further right to expand the border between the pictures. You can also adjust the background color of the collage by clicking the color palette box on the Settings tab.
The best format for desktop wallpaper is Current display. Select that from the Page Format drop-down menu. Click the Landscape button to orient the wallpaper horizontally.
To set up a collage with rotated images, select Picture Pile from the drop-down menu. That’s a collage which includes the images in a scattered pile. Configure the layout of the collage by left-clicking the pictures and dragging them to new positions. To rotate the selected photo, hover the mouse over it and then left-click and drag the compass point around the compass in the shot directly below. Left-click the compass point and drag the mouse right and left to expand and reduce the image.
Two options add borders to the Picture Pile images. You can select a plain white or instant camera border by clicking the Picture Borders buttons on Settings tab. The instant camera border is a good one to include picture captions if you’ve added them. Select the Show Captions option to include the text at the bottom of the image as below. To add new captions to the collage images, right-click them, select View and Edit and then replace the ‘Make a caption’ text beneath the picture with a caption.
When you’re done, press the Create Collage button. That will save it in a Collage subfolder. Now add the collage to Windows 10 background by right-clicking the desktop and selecting Personalize. Select Picture from the Background drop-down menu and click Browse. The collage saves at Pictures > Picasa > Collage. Select the collage wallpaper and click Choose Picture to add it to the desktop as below.
Set up a 3D Photo Presentation with Showcase
Showcase isn’t exactly photo collage software, but it’s something similar. With this you can set up photo presentations that have 3D effects. This program enables you to combine five photographs into desktop wallpaper. Open this page and click Showcase 1.0 to save its setup and install. Then launch the software’s window in the snapshot directly below.
The default number of images for these presentations is three, but you can select 5 Images from the drop-down menu. First, add your favorite photos to the wallpaper by right-clicking the picture boxes and selecting Set image. You can also delete photos by selecting Remove image, and adjust their placement on the presentation by clicking the Swap with image … options on the context menu.
Showcase includes three bars for you to configure the images with. The Offset bar moves the picture left and right. Drag the Distance bar left and right to expand and reduce the photos. The Angle bar adds that extra 3D effect as you can drag it right and left to rotate the pictures as shown below.
Below that you can adjust color of the presentation by selecting the Background check box. Then drag the bars there to customize the background color. Adjust that so it matches your taskbar and Start menu color scheme.
The presentations include reflections beneath each photo. Click the Reflections check box to switch that effect on. Then drag the Height and Opacity bars further to the right to enhance the effect as below.
Click File > Save as to save the wallpaper. Select a JPEG file format from the Save as type drop-down menu, choose a folder for it and press the Save button. Then you can add the 3D photo presentation wallpaper to the Windows 10 desktop much the same as the Picasa collage.
Set Up a Photo Collage Wallpaper with Fotor Web App
You can also set up photo collage wallpaper for the Windows 10 desktop with the Fotor Web app. This is partly a free app, but it also has an upgraded version that expands its options. Click here to open the website, and click Collage to open the tab in the shot below.
Next, click Import Photos to select the images to include in the collage. A sidebar on the right of the page includes thumbnail previews of the pictures, and you can drag and drop them into the photo collage boxes. To adjust the image dimensions, hover the cursor over the borders, hold the left mouse button and then drag the borders left, right, up or down.
To select alternative collage layouts, press the Classic, Funky or Artistic Collage buttons on the left vertical toolbar. Then you can choose a number of layouts that can include eight or more photos in them. The classic template sidebar has a Color & Texture button for you to choose alternative background colors with. Drag the Border Width and Corner Rounding bars shown below to expand the borders and add rounded edges to them.
One thing Fotor has that Picasa doesn’t is stickers, which add extra décor to the collage. Click the Stickers button on the left toolbar to expand the sidebar below. Then select a category to drag and drop some stickers onto the collage. Drag the stickers’ borders with cursor to adjust their dimensions, and you can also rotate them by clicking the Flip and Rotate button on their toolbar.
When you’ve set up the collage, click Save on the toolbar above the collage preview. That will open a window with a couple of save options and a Print button. Select Save to My Computer to save it to disk. Then add the collage to your Windows 10 desktop.
So collages are a great alternative to slideshows to show off some of your favorite photographs on the desktop. Picasa, Showcase and Fotor have plenty of options to set up collages with snazzy effects that can be terrific Windows 10 wallpaper.
