Version: (using KDE Devel) OS: Linux Since dolphin is meant to be as transparent and user-driven as possible it is a bug that showing previews does not only depend on the user's choice but some other settings too. If the user enables previews, i.e. clicks on the button in the toolbar he expects all pictures in the folder to be shown as previews. However this does not work in all cases because dolphin overrides the user's choice with a file-size setting. As a result the user does not know why some pictures are shown as previews and others not. In some cases none of the pictures in a folder will be shown as previews and the user will ask himself, why his command to do so is ignored. Hence the only transparent solution is to let the user decide whether previes should be shown or not, without any other criteria but the user's choice. The max-file size for previews should be removed from the settings and only the preview-button in the toolbar should enable/disable previews to make this functionality transparent to the user.
I don't know if it is a good idea. Maybe it should be better return a message which inform that "All images bigger than XXXMiB are not previewed." and "This behaviour can be edited in dolphin settings dialog". Anyway we are in string freeze. But it could be introduced in 4.1 :-)
Can I vote against it? It should stay configurable. E.g. on virtual systems I don't have much hardware space and system power so I prefer to only view thumbnails for files up to 2 MB to speed up the view and to preserve disk space. On real systems I prefer to see thumbnails for pictures even if they are about 100 MB size. But the idea of FiNeX is brilliant - for the 1st time user.
Since the scenario described in the comment above is not very common and "normal" users should not be bothered by people running linux in a virtual machine anyway, I do not think it is valid. If at all there should be an option in dolphn that allows the user to turn off previews for images larger than x MB. If that option is not enabled, dolphin should preview all images.
This could be an idea: add an option for enable/disable the size limit. Anyway should it be enabled or disabled per default?
In the meanwhile the message which inform the user about the limit could be already added.
The idea on bug #161862 could be the right solution :-) Remove the option is not a good idea.
Vote _against_ the original report.
#161862 looks fine to me. I just got by the current behaviour (http://bugs.kde.org/show_bug.cgi?id=178921), and definitely believe that the current behaviour leads to a poor user experience. I think that my suggestion for how to fix the user experience (in 178921) matches #161862, although the latter is stated more clearly.

Resetting assignee to default as per bug #305719
The maximum file size setting for preview has been removed. (For some file type previews the size doesn't matter) Instead every thumbcreator has to decide for itself how big files can be. This means it is still possible some files do not show previews if they are to big. But I'm not sure if this happens for files with common image and video extensions. Possible solutions to warn the user if this is still the case: -Show a small icon emblem (http://www.iconarchive.com/show/oxygen-icons-by-oxygen-icons.org/Status-dialog-warning-icon.html) in the corner of the icon. -In the file properties, Preview tab show a message explaining the file is to big. -...
As of today, Dolphin's previews have no maximum file size set by default, or on a per-file-type basis. It's editable by the user.
