No Icon Previews in Finder

Hi
Something has killed Icon previews in Finder. 'Show Icon Preview' is selected in 'Show View Options'.
I found elsewhere here that some of Rogue Amoeba's 'Audio Hijack Pro' plugins can cause this issue so I uninstalled the whole package after unsuccessfully trying to upgrade the plugins (which have now been fixed). Uninstalling the lot and rebooting did not help.
I've binned ~/Library/Preferences/com.apple.desktop.plist & com.apple.finder.plist and rebooted. This did not help.
I've also binned com.apple.QuickLook.thumbnailcache from /private/var/folders/somename/someothername/-Caches-
This has not fixed the problem. After rebooting, the quicklook thumbnail cache is never recreated.
Before my loss of icon previews I had multiple instances of quicklookd crashes. This no longer happens since removing the Rogue Amoeba plugins but I have many
'[QL] Can't get server port for <QLServer com.apple.quicklook>: Unknown service name' logs in the console.
I've also noticed that 'Quicklook Helper' is never running (randomly viewed from activity monitor), is this what generates Icon Previews in SL?
Any help Appreciated
Cheers - Mark

Wish I could offer help, but mine just started doing this as well. Mine occurred after a system failure (thanks to Windoze and Parallels) and a complete restore from Time Capsule/Time Machine. So far the only other odd thing I've noticed is my Trade Gothic fonts got corrupted.
I don't have Audio Hijack Pro installed.

Disable / Turn off Thumbnail / Icon Preview in Finder?

Can't find any new/recent posts to solve this issue. I want to disable/turn-off the little icon preview in finder.
I have to access a lot of images on a server at work. Image files(jpeg, eps, tiff, psd, ai, ect) that are typically 50MB and higher. So you can only imagine the amount of lag I get and the time I waste every time I click on a folder in list view.
Is there any way to disable it? Just have it show a standard icon file type instead of it loading 100+ 8MB images in little tiny icons?
I've already tried the View -> Show View Options -> unchecked 'Show icon preview' and applied it as 'Use as default'
Its turn off for all folders but it is still loading the mini icon preview.
(I'm on a Mac Pro - Mountain Lion)

I've tried reinstalling Mavericks and I'm still having this issue. I'm considering wiping my drive and going back to Mountain lion. Qucktime player in Mavericks seems to suck. I'm having several other issues playing back older quictime files. Most play in Quicktime 7 but a lot have no quicklook previews. The sheer volume of prores files I shoot makes this extremely inconvenient for me. How can Apple not support their own Codec????

Icon Preview in Finder

Under the View Option menu in Finder, I want to keep my Show Icon Preview option turned off. After every restart I need to go back and turn this option off again. Why won't this option just stay off?

I bet you're talking about column view. If you are, open a window in column view, select Show View Options (Command-J), and uncheck the box for icon preview.
There are different view options depending on whether you're in icon view, column view, list view, etc. Icon Preview is great in icon view, but not so useful in the other views.

Icon Preview In Finder Not Working Properly

Ever since upgrading to Lion I've had the issue of icon preview not working properly in finder. This mostly occurs with movie files such as .wmv files. Some take a long time to show a preview and some don't even show a preview. In Snow Leopard this was never an issue.
This also seems to happen in stacks as well. I'll get a greyed out box with a dsah borded. Seems as though it's the large files that do this.
Anyone have any ideas?

I'm experiencing the same thing but with all kinds of files that have shown a preview in snow leopard: pictures, PDF-documents, music (with album art). It seems that previews are not created automatically whenever I change the name of a file or edit it in any other way, the preview shows up instantly. Rebooting works, too.
This is really annoying and a little online search shows, several people are having the same problem. As far as I know, there's no fix yet.

Show icon preview in finder problem

the other day when i was using the cover flow in finder to go through old photos finder stopped showing the icon previews for all my photos. toggling the option to show the icon preview doesn't seem to be doing, any idea what might've happened?

If I can hazard a guess it's possibly a memory availability issue given that it has to generate a thumbnail of the images on the fly and may be struggling as you navigate through more and more images.
I've had this same problem for a long time. I thought it must be either a memory or free disk space availability issue because in my case it appears to be brought on by Photoshop CS3. After i use Photoshop for a little while, new icon previews stop being generated entirely, as if they've been switched off.
I now have 7 GB of RAM, with Photoshop capped at 72%. I've tried reducing that percentage and i've moved all Photoshop scratch files to other drives with no change.
I used to be short of disk space on my main drive and i thought it might be a virtual memory issue. But i currently have 32 GB available.
*I bring previews back by using Force Quit to relaunch the Finder.*
Then i have to move all the Finder windows back to the "Spaces" i had them in. 10 minutes later they're gone again.

Finder icon previews slowing finder

I work with a lot of pdf files, and as finder shows pdf icons as a preview of the first page it can take a long time before the content of a folder stabilises itself, ie: updates all icons with a preview of its content.
Its particularly frustrating if you are renaming a file, as you have to wait for all the contents within the folder to finish updating otherwise it keeps skipping off the desired file.
Is there any way of getting the finder to just show the generic icon of a file, rather than the preview? It would speed up the system no end.

Thumbnails don't slow down the Finder. The problem is in the view style you are using. The bug where you loose your file rename session when the thumbnails draw is a known bug in List View that has been around for a couple OS releases, it has only been made more prominant with the addition of thumbnails in List View in Leopard.
The solution is either switch to Icon or Column View, or while in List View press Command-J and uncheck the "Show Icon Previews" checkbox. The click the "Use As Defaults" button.
Hope that helps.

Icon Preview in Finder Replace Application Icons, Which Apps Will Now Open?

If you're a graphic designer like myself who uses multiple image programs it was extremely easy to see which app was used for each file... A Photoshop document displayed the Photoshop icon, a Preview document displayed the Preview icon etc. etc.
... But now alI I see are tiny previews of every document, which may be great for certain circumstances, but now I have the problem of Select All and Open... but various apps open all at once if they related to multiple apps. If I knew which documents were opened by what it would help me to determine whether a quick snap at Command-A along with Command-O would suit me. Currently it now doesn't as I don't wish for perhaps more than one app to open, AND dragging to the dock and hovering to open an app is a pain, too.
So, any suggestions?

I bet you're talking about column view. If you are, open a window in column view, select Show View Options (Command-J), and uncheck the box for icon preview.
There are different view options depending on whether you're in icon view, column view, list view, etc. Icon Preview is great in icon view, but not so useful in the other views.

Problem with icon preview in finder

Lately I have noticed the odd picture would not display in preview in finder. But today all of the jpg, pngs, and gifs in finder wont display, all I am getting is the default system image. Now I have show preview ticked in view options. I have deleted the finder plist file as suggested on a search for the problem online. But I am still having the problem.
The only images that show up as previews are the ones that have been created or edited through photoshop. But as I have thousands of pictures on my HD i cant run them all through photoshop.
Can anyone help or point me to a thread with a similar problem? Thanks in advance for any sugestions.
Oh I run Snow Leopard 10.6.8 on an intel imac

Download and run all of the free OnyX checks, maintenance and then cleaning and reboot at the end.
(Just one thing, don't delete the log files)
http://www.titanium.free.fr/
Also if any of the initial drive checks gives a error, report back and backup your files off the computer (Not TimeMachine) and disconnect.
This will flush your system and let things rebuild, test things etc., nothing gets deleted but you should backup your files off the machine regardless.

Icon preview in finder window

How do I get a thumbnail preview to show up as the icon when looking at a file list in a finder window?
I can't find any pref settings to that effect.
Thanks.

rileyman...
I was thinking along that line but the confusing part was putting it all into words. But the unfortunate thing there has to be some stripped data for it not to be seen there properly. Perhaps EXIF data, of which stands for Exchangeable Image File Format, that I am a bit clueless on any fixes. What I do know is that Preview.app is the worse for stripping that out on an export. Then the preview icon gets tagged into the picture rather than seeing the true picture from within the "Finder Preview Window"
What I do is to coral them up into single folder for opening within another application. iPhoto is ok at times, but I have more luck with Photoshop - Elements.
If you are photo application deprived, check over any camera, printer or scanner software that you have that may contain some freebies. Or feel free to see this website. There is a few image browsers there.

No prores422 Quicktime icon preview in finder OSX Mavericks

I upgraded to Mavericks osx 10.9 and now I no longer get a thumbnail preview on my prores quicktime files in the finder o. I do get a preview with any other type of quicktime codecs the only affected files are prores files. I shoot a lot on the blackmagic cinema camera and it's not good for me just to see a Q on those thumbnails. I'm a Final Cut Pro X user so I have the proper codecs to view the files. I have tried the view options and it does not affect Prores files. I've also downloaded the latest codecs from apple. So I want to know I'm I the only person this is happening to? I'm thinking I may need to reinstall mavericks but before I do that I need to know if anyone else is experiencing this? I have attached a screen capture to illustrate what I'm talking about. Quicklook does still work on the prores files but I need that thumbnail.

I've tried reinstalling Mavericks and I'm still having this issue. I'm considering wiping my drive and going back to Mountain lion. Qucktime player in Mavericks seems to suck. I'm having several other issues playing back older quictime files. Most play in Quicktime 7 but a lot have no quicklook previews. The sheer volume of prores files I shoot makes this extremely inconvenient for me. How can Apple not support their own Codec????

Can you Choose a Particular Frame for Quicktime Icon Preview?

Is it possible to choose a specific frame for a Quicktime file icon preview? A lot of movies start out with a black frame and the icon preview in Finder is therefore a black square. I would like to be able to choose the frame to use for the preview.

I don't know if this is possible (ask in the QT forum) but you can trim the movie with QT player to get rid of the black frame at the beginning of the movie. you can also take a screenshot of any frame you want and apply it as a custom icon to the movie.

Don't Show Icon Previews

I've recently upgraded to Snow Leopard from Tiger. Everything has been a little glitchy, but the one thing that is truly annoying me is the Finder will always show Icon Previews. Every time I log in and open a Finder window, I have to go thru the View Options and uncheck Show Icon Previews. The next day, I have to do the same thing, because the Finder does not remember that setting.
I've tried Option-clicking and Command-clicking the check box, but it hasn't made a difference.
Does anyone have any suggestions as to how I can get the Finder to remember that I don't want to see Icon Previews in Finder windows?
A preemptive thanks.

Baltwo, per your suggestion:
I created a new administrator account, logged in, opened a new Finder window, hit command-J, unchecked Show Icon Preview, closed the View Options window, closed the Finder window, then logged out. I logged back into the new account and the settings had stuck. (Yea!?) I did the whole routine with my own account and the settings were reset, with Show Icon Preview checked. Hmm.
So I guess it's some glitch in my user account. Any ideas how to fix it? I'm not really excited about creating a new user and having to set up all the preferences and whatnot, but I guess it might be weighing that inconvenience against the annoyance of the Icon Previews.

OS X's icon preview doesn't match JPEG

Hi all,
I have a few photos that were passed to me. In the icon preview, they were the original photos. But when I opened them in Preview or iPhoto, they were the Photoshopped versions.
Anyone know what's going on? And how to extract the icon previews?
Thanks!

But when I Get Info on the JPEG, the icon shown is for the modified image.
Additional info that I stumbled upon:
When resizing the icon preview in Finder, after a certain (larger) size, the icons would change to the modified versions. Shrinking the icons would bring back the original unmodified versions.
Really strange behaviour...

Preview in Finder not loading. All my images have the Preview icon instead!

Hi,
anybody experiencing the same problem as me?
All of a sudden my preview in finder doesn't work and all my picture preview icons became the "Preview" icon itself!
Here is how it looks like.. : http://img146.imageshack.us/img146/3414/picture37.png
Does anybody know how to get it back to normal because it is such a hassle to click on every single photo to find the picture that I want!
Thanks!

Sounds like your LaunchServices database has gotten corrupted. Launch the Terminal app in /Applications/Utilities/, copy & paste this one-line command into it, hit the return key, and restart.
*/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchS ervices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user*
That should fix the problem.

Icon Preview Problem in Finder

Hi,
I've had my new MacBook for about a month now, and as my photo collection has grown I'm starting to notice that while using CoverFlow (which I have as the default view for most of my folders), there are always some icons that appear as a generic JPEG icon instead of having the image preview. This problem goes away (all icons have previews) once I open the same folder again or refresh it somehow (for example by selecting Calculate All Sizes in View Options). However, once I restart/log in again, it happens again. Most of the images are normal JPG's from the web, and which ones have missing previews is completely random. This applies to all of my folders, and I've seen the same thing on several other Macs as well (the family iMac and several others in Apple Stores). This only appears in CoverFlow view, though.
Here are a couple of screenshots to illustrate the problem:
http://i92.photobucket.com/albums/l4/Octavarius/Screenshot-IconsinFinder.jpg
http://i92.photobucket.com/albums/l4/Octavarius/Screenshot-IconsinFinder2.jpg
Does anyone else also experience this issue? Is it a common issue? The Show Icon Preview option is checked, by the way.
Any ideas?
Regards,
Jacob

Keep in mind that it's the icons below the Cover Flow section that are the problem. The blurry photos in the Cover Flow section on the first screenshot have very small resolution, that's why they're blurry, but if you look in the second pic, you'll see some others that are completely sharp. Just in case you misunderstood.
I do sometimes get blurry pictures in the Cover Flow section, just after they're downloaded, but once I log out and back in, they're fine and stay that way.
Once I click Get Info on an icon that's missing the preview it's immediately refreshed and the preview is there again, as it should be. It seems like Finder is sometimes skipping certain previews the first time you open a folder since log in.
What did you mean by custom icon? How do you set/delete one?
