Preparing Your Photos
Save as JPEGsJPEG format is preferred for all photos.
Rename your photosMost digital cameras give your photo non-descriptive name such as IMG_3284.jpg which is not very helpful. Changing the name to something useful makes sure it's easy for everyone to understand the content of the photo and it helps to boost the search engine optimisation of your images.
For example, if you have someone from your business in their office writing on a whiteboard, you would make the image named something like: simon-kelly-office-whiteboard.jpg
