Most slides that look amateur don't have bad photos. They have good photos used badly: a busy image with a headline sitting on top of the busiest part, text that vanishes against a bright sky, or ten slides with ten unrelated colour schemes.

Choosing images for a presentation is a different job from choosing a photo to look at. The image isn't the point — your words are. Here's how to pick images that support them.

Start with the space, not the subject

Before you think about what the photo shows, look at where the empty space is. A slide background needs a calm area — sky, a plain wall, soft blur, open water — big enough for a headline and a few lines. If the only empty space is a sliver down one edge, the image will fight you on every slide.

That's why dedicated backgrounds are often a better starting point than photos: textures, gradients and soft patterns are built to sit behind something else. The backgrounds category on Stockphoto.now is organised the same way — colour and texture made to carry content.

Crop to 16:9 before you do anything else

Almost every presentation today is widescreen 16:9. A portrait photo won't fill that without losing most of its subject, so check the orientation first. Crop to exactly 16:9 with the Aspect Ratio Crop tool and decide where the subject sits — usually one third in from the side, leaving the rest for your text.

Make text readable, always

  • Blur it. A soft Gaussian blur turns a busy photo into a background while keeping its colour and mood.
  • Darken or lighten one side. A subtle gradient or vignette behind the text area does more than a heavy drop shadow.
  • Check contrast. Put your text colour and the background colour into the Contrast Checker. People at the back of the room, and anyone with low vision, will thank you.

Keep the deck consistent

Pick one colour family for the whole deck and stick to it. Run your first image through the Palette Extractor, then look for the rest of your images in the same range. If one image is close but too cold or too warm, the White Balance tool brings it into line.

Consistency matters more than any single image. Five average photos in the same palette look designed; five brilliant ones in five palettes look random.

Keep the file size down

A deck full of full-resolution photos can easily grow to hundreds of megabytes — slow to email, slow to open, and prone to stuttering on a borrowed laptop. For a 1080p screen you rarely need an image wider than 1,920 pixels. Resize, then run each image through JPG Compressor before it goes into the deck.

Credit where it's due

Check the licence for every image, and credit where the source asks you to — a small line on the slide or a credits slide at the end both work. How to attribute an image has examples. For where to look in the first place, see Where to Get Free Stock Photos.
