The APNG spec[1] uses the term "default image", which is probably what "poster frame" means here, but it's not at all clear. Perhaps the spec should mention "default image" here and link to [1] or otherwise explain "poster frame" by saying, say The poster frame of an image in an animatable image format is what's displayed when 1) animation is not supported or 2) animation is disabled. Not sure if this makes sense in other formats, but well. [1] https://wiki.mozilla.org/APNG_Specification
