Hello Gerrymac,

I would go for GIF  for images that are not photos. JPGs tend to be blurry around the edges. PNG is an alternative, but GIF will give you a good quality/size ratio.

cheers, teylyn

JPEG will give you more colors and more control over the compression rate (the more you compress the more the picture gets ugly)

GIF will only show 256 colors (i.e. it is 8 bit)

PNG will show about 16 million colors (i.e. it is 24 bit)

So, I'd choose PNG and if it didn't provide a reasonable compression I'd go with JEPG

Well, I didn't say why. PNG is loseless compression so it would keep the image/chart as is without changing its colors while JPEG (or JPG) is lossy so to it reduces the number of colors displayed to save file size.
