... I'm not sure it is a good idea to honor image's "dpi" setting
yesteday I applied a jpg that, inadvertantly, forgot to check and found it was set to 500x500px *and* 600dpi. result: *in Tag's "cover preview"* the image was terribly small
re-saved with a 72 dpi setting and all was fine
but there might be a good reason to honor dpi that I'm missing
