No I don't think anyone even was interested in it.
If an image is of interest it is normally loaded as png, if it isn't interested, it is not loaded.
Is there any real reason to check a million of images for their sizes? You have "media declaration files" that should give quite a plain description of loading what and when ... so there is no real reason to get such information without loading the rest as well (as that is the largest part of the work anyway ... get to the point to read the header ... the rest of the image can normally be read "for free" after that on todays harddisks & ram)
