Exporting Excel graphs to folder (best macro, best format)

I know this is a fairly common question, so feel free to redirect me to a similar thread. But I need some lines that export graphs (I have about 50) in the best way to a destination folder, with the best quality format. (I was told GIF would be?).

Thanks all,

I have a resizing code right now that isn't giving me the greatest quality as well, so if possible can you add the resize lines as well.
