The default image formats for new websites are JPG and GIF. In general, all new images you upload should be sized and optimised to suit the following example guidelines:
•Format: .jpg | .gif | .png
•Resolution = 72 dpi
•File Size = 1kb>25kb (recommended)
Note: The permission to manage images and folders comes via the administrative task of assigning Image Manager rights to the role.
Tip: You can also optimise your image within the Image Manager when you upload images, based on the default system settings.
