The Resource Gallery on the left side of My Memories Suite allows you to add elements to album pages quickly. The panel shows the thumbnails of all the elements in the current folder or category. The name of the folder or category appears near the top of the pane.

Click the icons at the top of the pane to select which gallery to view:
To add an element to a page, click on its thumbnail, hold down the mouse button, and drag the mouse to the page canvas. You may also double-click on the thumbnail. The element will appear in the middle of the page.
Some gallery options will allow you to change the current folder or category. Click on the Select Folder or Select Category button above current folder or category name and browse to a new folder or category (click on plus or arrow symbols to expand folders in the folder selection window). Click on the folder or category to load thumbnails of the elements it contains.
Photos: If the current page has an unfilled photo box, you can fill the box by dragging a photo thumbnail over the box. The box will highlight in yellow to indicate that it will be filled. When you release the mouse, the photo will be placed in the box.
