Photo Tips

  1. Be sure that all images are sized correctly for their purpose.
  2. Always resize images in an image-editing program in their original format.
  3. Set the resolution to 72 dpi. Higher resolution will not provide a sharper picture, just a larger file.
  4. Provide an ALT tag for all photos.
  5. Include the credit information for all photos.
  6. Select the correct file type for maximum optimization:
    a. Photos – .PNG, .JPG (.JPEG), or .GIF
    b. Images – PNG, .JPG (.JPEG), or .GIF

Useful Information

  1. GIFs are best for flat color images with no gradients.
  2. GIFs provide the lowest file size for images that have flat colors and no blends. They can also have transparent backgrounds.
  3. Photos can be saved as either PNGs or JPEGs. PNG photos tend to have larger file sizes than JPEG photos.
  4. There are three (3) types of PNG formats: PNG 8, PNG 24, and PNG 32. PNG 32 is the format for transparency and will sometimes yield a higher file size than PNG 8 or PNG 24.
  5. PNG 32 offers the best option for any images requiring a transparent background.
