Currently one can "turn on" previews for images smaller than x MB. If the settings were slightly reworked they would enable dolphin to both show previews for all pictures as well as limit previews to a max file size. Currently only the latter is possible.

[ ] Disable previews for files bigger than x MB

This enables previes for all images without having to set the mx file size slider to some randomly high number like 999MB and at the same time allows to restrict previews to a certain file size.

Of course I would opt for not having that checkbox enabled by default, but that's another bug. (bug 154855)
Comment 2 FiNeX 2008-05-12 11:10:48 UTC
I've had the same idea too :-)

This could be the better solution!
Comment 3 doc.evans 2008-12-29 17:21:57 UTC
I agree that from a user perspective the best solution is to have this option, and for the box not to be checked. (See also http://bugs.kde.org/show_bug.cgi?id=154855 and http://bugs.kde.org/show_bug.cgi?id=161862).

Problem longer exists in KDE 4.6.3; the Previews tab now contains the following spinners:

Do not create previews for
Local files above: x MB
Remote files above: y MB

Should this report be closed now?
Comment 8 S. Burmeister 2012-01-05 11:17:17 UTC
No.

It is still not possible to enable thumbnail creation for all pictures without setting some randomly high number for "MB". the latter indicates that the user still has to work around the bug and hence the bug still exists.

There is no way to disable/enable thumbnail creation – one can only set a size limit – until there is a checkbox as described in comment 1.

Resetting assignee to default as per bug #305719
Comment 10 Maarten De Meyer 2013-08-11 15:12:54 UTC
The Local files above setting has been removed. Maximum file size is now up the thumbnailers but I do not know if these have implemented a size check already.

Hi Martin -- I do not really handle remote files. Why was the local files settings removed? Recently I have been downloading some heavy TIFF images re map data and even if my cursor stays on the filename a bit the whole system gets hanged temporarily because the app is trying to produce a thumbnail.

It is not clear to me what you mean by "thumbnailer". Is there a separate application which creates the thumbnails where I have to go change the setting? IMO it is silly to have to go to another application to turn off previews within Dolphin.

A 'thumbnailer' is a small plugin that creates the previews for a specific file type.
The author of this plugin should implement a file size check. (if that is the cause of your problem)

If you want to turn .tiff previews off you can go to dolphin preview settings and uncheck image files.

Because it was wrong. For some file types the size doesn't matter because a preview can be generated very easy.

Such as for text files, fine. And even for images if a thumbnail is embedded, I guess.

Anyhow, please indicate where in Dolphin settings I should go to configure the thumbnailer plugin to make it NOT produce thumbnails for images of more than a given size. I am not able to find any plugins pane in the Dolphin Settings window.

Duplicate of https://bugs.kde.org/show_bug.cgi?id=154855, which is resolved in the latest versions of Dolphin.
