Bug 156046

Version:            (using KDE 4.0.0)
Installed from:    SuSE RPMs

The information panel is useful, but the previews it shows are very small even at their largest size.  It would be nice to have an option where the preview would automatically resize to fill as much of the information panel as possible while not changing the aspect ratio and not going over the real size for images and videos, if we ever get the option to preview videos.  In other words, the preview will grow so that it keeps the same aspect ratio, neither of its dimensions are larger than those of the original file, and neither of its dimensions are larger than those of of the information panel itself (leaving room for the text part of the information bar and an appropriate margin, obviously).  

This should probably not be the default behavior since it would take more memory and would also be incompatible with cached thumbnails and thumbnails stored in files, but it would still be a very useful option.  Further, it could at least provide a very simple makeshift slideshow without having to increase the complexity of dolphin for the end user in any way.  Just making the information bar very large relative to the main browser would accomplish this (although allowing the information bar to be above or below the browser would work better still).  More complicated options, like whether to stretch the image or change the aspect ratio, would be left to dedicated image viewers like gwenview.  As far as appearances would go it would look not different and have no more options than the original information panel, only the size of the preview would be different (and even then only if the panel were resized).  The option could be as simple as a "resize preview to fill information panel" menu entry or toolbar button.
