Finder Cover Flow image preview size is small, cannot be adjusted and showing empty blank previews in Mavericks

When using Cover Flow the image preview in the main window (not the thumbnail list at the bottom) images appear but only use about 1/2 of the window space available. It is also showing black/blank preview images as I scroll through the files even though they are cached.
I enlarge the Finder to fill my 27 inch display, slide the size adjustment handle (three lines under the file name preview) all the way down as far as I can. The preview only enlarges to a certain point leaving the upper half of the window unused. I wish to enlarge the cover flow preview images to use this window space even if it affects the overlapping or number of cover flow images avaialble in the window. I am assuming this is becasue of the nature of cover flow showing the two previous and two following images to the left and right of the previewed image. As I scroll left and right occsionally one of the upcoming images will appear as and empty preview as well. It's all goofed up.
Hoping for any suggestions.
I have seen articles about using terminal to adjust "flow height" but never anything substainial that seemend like an informed solution.

I also would like to know if there is an answer to this. My landscape photos always display with a third of the cover flow window as blank empty space (matching your screenshot). This seems like such a waste. Is there any way to change the "padding" between the top of the finder bar and the cover flow preview?

Cover Flow images don't fill Finder window?

Hi everyone,
I like to use Finder in Cover Flow mode to browse through images. However, if I expand Finder to fill the whole screen, and I expand the Cover Flow pane to take up most of the screen, the Cover Flow images don't expand to fill up the Cover Flow pane. I have the High Res screen, so maybe it looks normal on a lower res screen but I think it's odd that Cover Flow doesn't try to expand the images to fil the space. Is this behaviour normal and is there a way to change it?
Cheers,
Jim

Solved the problem myself. I retyped the name of each folder (same name) under Pictures and added a space plus #1 after each folder name. Images appeared almost immediately on the content pane after that was done. Later I will then open up on my hard drive, under Cover Flow, two windows....one from the Pictures Folder and the other one from the Window Documents that contain the images transferred from an old hard drive. I will then select the images I want to keep and drag and drop the images from the Window Documents to the sub-folders in Pictures and that should do it. Attempting to do it from within Bridge will cause the images in Pictures to disappear so this other way is safer. Then I will trash my Window Document folder when I'm done. If anyone has experience this problem this might be a way to see if my solution might work for you. (I formerly had a window system and now have a iMac).

Does Finder cover flow ignore monitor profile/wide gamut for JPG?

Hi,
beeing a proud (?) owner of a wide gammut display I use a special monitor profile to see correct colour which of course only works in applications which support it. I expect the Finder to be such an application at it mostly is.
ButI found on my System with Lion 10.7.3 that my JPGs display wrong/oversaturated in the finder cover flow.
This is independant of embedded or not embedded ICC profiles in the JPGs, but just an issue with the selected monitor profile.
The error is NOT observed e.g. for JPEG 2000 files!
The error is NOT observed for other image display options within the finder, so only the cover flow is effected!
Further I can not remember to have seen it earlier in Snow Leopard.
Can anybody also see this issue?
Thanks for any feedback!

I don't have a Wide Gamut monitor, just a 24" iMac/2007, here one jpg in Preview on left & Cover Flow on right...

Strange sparkling graphics glitch in finder cover flow view!

Hi there,
Recently my finder cover flow view has been displaying what can be described as 'sparkling' effects around the folders/icons when i move from one file to another (sparkling stops when movement of icons does). The sparkling effect can be described as small white dots flashing then disappearing at random points on the black background of the cover flow view. This does not happen all the time and seems to be more prevalent when there different icons next to one another. just wondered if anyone else is having this issue and if anyone can offer me some advise? Thanks.

It happens... See http://samsoft.org.uk/iTunes/grouping.asp for more.

Cover flow images

cover flow images look terrible, like out of focus, like being displayed in a different resolution. images are higher than 1024x798. is the a setting somewhere to adjust this
new to the mac osx just installed 10.5

It's not that simple. If there is no preview it does indeed create one, but mine are really poor quality. If there are existing previews it seems to use those. The image used in cover flow is not (necessarily) the one you get when you select Get Info. I've found some where the image is completely different because the image got edited at sometime and one of the previews never got updated. I've no idea how to fix this easily though.
I found some files that had reasonable previews in cover flow, but now they've been replaced by poor quality ones.

Finder Cover Flow Background

Has anyone noticed the Finder Cover Flow Background in Lion is very distracting? Let me explain... On my MacBook Pro, mid 2009 (with or without the Cinema Display attached) it shows up as a "glowing gradient" where the white is very overpowering. I also put Lion on my daughters MBP (which is older) and hers looks very normal. Seems odd, but I'm confident that someone has a solution.
I've been researching and havne't found any answers. It may just be that I'm not searching correctly for the answer!
Does anyone know how to change the cover flow background to a solid color? Also the text under the icon shows up dark and hard to read (not a biggie there though). I tried also to look at the finder defaults in Terminal to see what there might be and didn't see anything.
Any help would be greatly appreciated. It's an annoyance and nothing more than that.

You're correct, that would help!!!
It's a nice Hollywood effect.
Here's a screen shot of cover flow from my iTunes. Notice the nice black background (and EWF).
Something had to get changed somewhere because the text is black also. This was a fresh install of Lion on a newly formatted drive so I can't blame it on leftover stuff from SL. I haven't run any scripts or anything to change things so I thought maybe there was something in System Preferences and didn't know it. I spent a while looking through it and found nothing.
Again, your help is much appreciated.

Cover Flow image different from

Most of the time, the album artwork in Cover Flow is identical to that on the thumbnail image in the bottom left corner of my screen (sorry - don't know the correct term for it). However, on occasional tracks they're different.
I think I know why, but don't know what to do about it...
I have a huge collection of old singles that I digitised. There being no album title, I created one called Singles and it keeps them all together. The thumbnail image always varies with the track but the Cover Flow image only displays the artwork of the first track by that particular artist (so for example, the Cover Flow artwork for all Elvis Presley singles is the same, and it's the first one in the list).
I'd be grateful for any ideas for how I can correct this?

Well, I'd have to set something up like that to check....but I don't have a bunch of singles hanging around.
The closest I have to it is Tori Amos' +Strange Little Girls+. Each track has a different picture on the actual CD, so I scanned those in.
Cover flow shows the artwork from track 1. The other tracks only show their specific artwork when they are selected, and only becaue I went to the artwork tab and dragged around the images so the one I wanted was first in thebox.

10.9.3 finder cover flow doesn't save image size

I went from Snow Leopard 10.6.8 to Mavericks 10.9.3. Everything went ok, but I have one annoying problem though.
Everytime I open a cover flow window in Finder I have to resize the image preview section. The Finder window size is saved,
but not the actual image size of the cover flow. It always goes back to a default, very small, size everytime I reopen the Finder window.
Didn't have this problem in Snow Leopard. It worked great. I just know one other person with the same problem. He just bought his MacBook Pro with Mavericks
and I am on a late 09 MacBook. So it shouldn't be a problem with just my Mac and Mavericks.
So my question is;
Will there be any solution to this soon? Maybe a program update to be released, regarding this issue?
Thank you for any feedback!

Ok, more information for anyone that might care. The wake-up seems to be the familiar dark wake in order to go into hibernate mode. Except now, it's a death wake. Looking at the logs, I see that it happens exactly 70 minutes after sleeping, even though hibernatemode = 0 (which shouldn't hibernate at all!)
So my power settings look like this:
Currently in use:
standbydelay         4200
standby              1
halfdim              1
hibernatefile        /var/vm/sleepimage
darkwakes            0
gpuswitch            2
disksleep            10
sleep                10
autopoweroffdelay    14400
hibernatemode        0
autopoweroff         1
ttyskeepawake        1
displaysleep         2
acwake               0
lidwake              1
standbymode is 70 minutes, what a coincidence. I'm going to try setting it to 0 and see what that does.

Wrong preview in Finder Cover flow

Custom Icons Disappear in Cover Flow Above Certain Size

I've been trying to create custom icons for certain folders and I've been having no luck when viewing them in cover flow.
I've downloaded a PNG file, 512x512 pixels. Open it in Preview, copy to the clipboard, do a 'get info' on the folder I wish to change the icon of, click the little icon, hit paste, and it appears correctly in the preview and in the finder Icons view, as well as on my desktop or whatever. However, if I turn on cover flow and drag the size of cover flow to larger than a certain point, the custom image disappears and all I get is a blank spot. It's as if the 256 pixel icon is being created but the 512 pixel image is being left blank.
I do not know if this happened in 10.5.1, as I hadn't tried until after installing the 10.5.2 combo update.
In the following picture, you can see 1: bottom right, a preview of the png file itself as it appears, correctly, in cover flow, 2: top right, the icon working correctly on the desktop and in the get info window, and 3: left: the cover flow view of the computer showing a bit gaping void where the custom icon should reside.

Any ideas? Thanks in advance!

This does NOT happen if I use an existing, working icon (say, put the Applications folder's icon onto my hard drive.) It seems to be an issue with custom icons only, not just changing the icon for something.

Finder Cover Flow is broken and doesn't show the correct file I click on

When I go into my Downloads and press the spacebar to preview a photo, it will preview the photo before it for some weird reason.
Example:
I highlight and press space for "Photo 2", but instead it will show "Photo 1" in the Cover Flow and will Preview that instead.

Totally broken for me too. This is a giant, gaping hole in the OS LOL. I fire up a Finder window w/ cover flow view, erase a file, and now the highlighted image in the list below is off by one file and it doesn't remove the preview of the just-deleted file in the Cover Flow pane. Sad. This is just an embarrassing bug Big A. How do you not fix this before going public with a major point release? Not to mention the scrolling issue.

Large file Tiffs are pixelated in finder-cover flow

50MB tiffs are very pixelated in the finder
in LEOPARD
(cover flow )
this is a bug i guess

I dont know much about file formats, but TIFF is fairly complex, and if it has space for an image preview, it could very well be that the preview has a low number of pixels and thats what's being displayed in cover flow. Not sure though. Have you tried re-saving the files in TIFF format with preview options turned off?

Changing Cover Flow images for a video

Is there a way to change the image of a video in Cover Flow? For instance, I have a mp4 video of my little cousin on his birthday as we all sing Happy Birthday to him. When I am using finder, in the folder with the video, and I switch to Cover Flow mode, the preview is a still image of the video. Instead, I want it to show a jpg photo I have of him blowing out his candles. I've changed the icon to the jpg, but I can't figure out how to change the image in Cover Flow.
Any help would be greatly appreciated. It would be a fun way to organize a lot of family videos I have.

You need to trim the clip in a video editor and then add it to the slideshow.

Finder/Cover Flow
