The photo upload feature on Travellerspoint has been upgraded to allow images in gif and png format.
Now you can upload files in gif and png format as well as jpg.
Both these formats can be particularly useful when designing a blog. Most photographers will work with jpg, so it won't affect photo uploads a great deal. But when saving graphics, both png and gif have certain characteristics that make them preferable at times.
My Mac saves screen grabs in png format, so this makes it easier to upload them to Travellerspoint if I feel like it
