If I select a png file, for example, the Information Panel shows me the dimensions of the image (640x480). But if I select a jpg image the dimensions are not displayed. I therefore need to click on the image file and Gwenview shows the dimensions. I have not tested many image file types, but it makes sense that they all should have their dimensions listed in the Information Panel, but especially jpgs.

I agree. It seems that currently the provided meta data system only reads the dimensions from JPEGs EXIF data...

SVN commit 927542 by ppenz:

* Use Nepomuk for getting the meta data instead of KFileMetaInfo.
* Use a QScrollArea widget to embedd the meta data, as Nepomuk provides so much meta information that it might not fit into the panel.

Open issues:
* Add the possibility to configure which kind of meta information should be shown.
* Check whether the receiving of the meta data for one file also might block the UI like when using KFileMetaInfo in combination with strigi.

I still have this problem in KDE 4.5.1.  Gif and png show dimension, jpeg does not.
Comment 4 Peter Penz 2010-09-17 14:56:49 UTC 
@Todd: The root cause for this is in the corresponding metadata-decoder provided by strigi. It worked in 4.5.1 for JPEGs that contain no EXIF-information or an EXIF-information with valid width/height, but did not work for JPEGs that have EXIF but no width/height in it. I created a patch for this in kdesupport and I think this should be available in 4.5.2 (kdesupport has no explicit 4.5.x tags, so I'm not 100 % sure).
