Preview picture display sizes weirdness

In Mac OS 9 The Blue Meanie used to use QT Pictureviewer as his default image viewer app and it worked groovily. But when he upgraded to Mac OS X and started using Preview instead, weird things started to happen.

Jpegs sometimes display and even print in a strange shrunken format (ie in roughly thumbnail rather than actual size) - and sometimes they don't. The shrunken size particularly happens with images taken from websites, and the only thing to do when it does occur is to zoom in the viewing size and drag the picture wider - or export it as a QT image - both fiddly and irritating.

Preview has no preferences I can set differently. This never happened with PictureViewer. Anyone got any ideas?

Come to think of it, this is something I've only really become aware of over the last couple of months. Is it a bug in X 10.1?

    starfleetX strongly recommends The Blue Meanie change to use GraphicConverter as The Blue Meanie's default image viewing program. GraphicConverter is far more customizable regarding defaults for opening files.

    Whyatt Thrash is of the experience that preview sorrily enough displays image files in its "true" resolution. Ie, if a 400x400 image has a resolution of 300dpi, preview will default to showing it as a 100x100 (roughly) pixels image. Pressing Command-arrow up a few times should display it at its true onscreen-size. Printing it at its onscreen size should be impossible to do from any app though, without converting it first.



    The Thrash-man has spoken.

    Why, Apple, why? Pictureviewer worked fine. Why complicate things?

    The Blue Meanie appreciates the tips, Wyatt and Starfleet
