    Default JPEG tags

    The media that seems to have the least support from Mezzmo are photos. Not only are EXIF tags (EXIF is the photo industry standing tagging for digital photos -- all digital cameras, smartphones, video cameras and so on write EXIF data into their image files) largely not read, but the active and other playlist tools refer only to music tags such as "Album/Artist" etc.

    I'm trying to display a 10,000 jpeg photo collection and the only useful information that it can be displayed on is the year tag. Or perhaps I'm missing something?

    The current version of Mezzmo (v3.0.2.0) does read some EXIF & IPTC tags (originaldate/datecreated/datetime, artist/author, description/caption/comment/model) but I agree that there are many more that Mezzmo could read and make available for organizing your photos.

    What EXIF tags are you interested in?

    Paul,

    My main interest is being able to sort by the freeform "tags" that I have inserted in my photo files mainly by Windows Photo Gallery. WPG allows editing of a number of tags (including the key EXIF ones), and it also allows tagging to, for example, an individual or individuals shown in a photo. I suspect in reading about this, that it is using the Adobe XMP standard, since there doesn't seem to be any practical limit on the number of these "tags" that can be added to an image file.

    Recent versions of WPG allow tagging to people's names in addition to the general descriptive tags. However, these additional tags don't seem to be read by other DLNA servers (twonky mainly), or perhaps interpreted by DLNA renderers (mainly Panasonic TVs and WD Live media players).

    The WPG software is of course widely used since it was free and included in Windows Vista, and freely downloadable since then for any version of Windows (variously called Windows Live Photo Gallery, Windows Photo Gallery).

    HP also ship a photo gallery editor on their workstations, and it appears to also be able to read and tag in a compatible way with Windows Photo Gallery.

    The straightforward EXIF tags showing camera used, for example, are also useful for sorting a display by source of photos. (For example, a slideshow of slides from one of my kids Nintendo DSis).

    And finally, the EXIF tags that show photo rotation need to be read and served since you get upside down photos on any slide show if you don't observe the correction you've made by rotating the image on WPG.

    Be interested in your thoughts about these. Happy to provide some samples if that's useful.


    Regards,
    tony
