TIFFs are big and are unsupported by browsers, as far as I know. Can't imagine LZW, layered or CMYK TIFFS being of much use either.
Do what I do: copy and paste it into an image-editing app and resave it down to a suitably-sized GIF or JPG. It's no big deal.
Easier than your method is opening the .tiff file in preview and then File->Save as. You then choose JPG as the format. No copy and pasting.
I am completely acknowledgeable about the technical part of things.
what does this mean? do you mean you know about technical stuff or not?![]()
