Composite photos _ These are photos with text or other graphics superimposed on the photo. I do this a lot with the quotations I post on social media and put into my newsletters. Import a photo into PowerPoint and expand it as large as you can on a slide. "Insert Shapes" and insert a text box onto the slide over the photo. Type the text you want to superimpose onto the photo and set the text color so that it contrasts nicely with the photo as background. Group the components and you have a composite photo.
Alternately, you may select an entire row by moving your mouse to the left_most cell in a row. When the cursor changes to an arrow, click the mouse and the entire row will be selected. You may select an entire column by moving your mouse to the top_most cell in a column. When the mouse pointer changes to an arrow, click the column and all cells in it will be selected. Once the desired cells have been selected, you may apply formatting changes to your selections as desired.
