Homepage Sliders

For something like a homepage slider, we recommend staying in the range of 1440 x 500. Not too tall and not excessively wide.

Full width and Full height images

For a full width and full height images like a background for a page, we recommend staying around 1920 x 1080.

This means you are natively at full resolution on an average sized modern monitor.

Image File Size Optimization

JPG Images

Make sure the files are compressed at 40% JPEG Quality in Photoshop (ideally in the Export As or Save for Web windows)

PNG Images

Run the images through a compression service such as TinyPNG.com to cut the file size of your images drastically without losing quality. This means your images load faster.
