On my machine Cornice cannot read up, display, or otherwise handle any JPG that has been output by Picasa 2. It throws up error msgs whenever it encounters one. JPGs straight from my camera it can display, as well as other graphic formats (BMP, GIF, etc.). Disappointing, as I was looking forward to a small footprint viewer.
(Sorry, but, I couldn't locate a Support listing for Cornice amongst the others.)
Picassa 2 is one of only 2 image editors we've found that messes with an image's EXIF data in a way that Cornice can't handle. We're actively seeking a Python developer to pick up Cornice development for us but, until then, there's not much you can do about it.
Sometimes, the impossible can become possible, if you're awesome!
Thanks for the heads-up, JTH.
Even though Irfanview Portable (IVP) is not OpenSource, IVP (4.20) still integrates into PA Menu without a worry. ("Yes, yes, anathema at its worst!")
Even if its Slideshow.EXE file is moved to a daughter folder (to keep down unnecessary clutter on PA Menu's non-resizable window), IVP still successfully locates its Slideshow.EXE file there, and runs it. I'm not advocating it, but it's only a 1.47MB footprint for what (for me at least) has been a very stable bit o' code for years, one with no hiccoughs.
