Viewing image dimensions in Finder

This may be an obvious question, but how can I view the pixel dimensions of images in Finder? I am new to the mac platform and I know in windows you can simply hover over the thumbnail in Explorer and it would tell you the dimensions of the image.
The only way that I have found the pixel dimensions in OSX is to open the pictures in preview and then "Get Info"

In List View, no. Sorry!
In Column View, open up the View Options and check "Show Preview Column". Click on an image, and in the Preview column, under the preview, there should be a list of information. The item marked Dimensions has what you are looking for.
There's also a way that works for all three views that involves the Get Info pane *in Finder* rather than in Preview. Click on an item, and hit Command+I. Open up the "More Info" section of the Info window (at the far left of the screen), and the Dimensions appear.

Cannot read pre-view cache

At startup I get failure message "cannot read from pre-view cache (förhandsvisningscache in Swedish)" every time. According to the message, the failure is supposed to be rectified at next start-up, but this has not happened. I simply cannot start Lightroom.

Thank You so much! Will try that.

That message is indicating that four previews have been corrupted. If you delete the previews file Lightroom will rebuild them the next time the files are selected. If you wish you can do them overnight if you have a large catalog. The previews file has the same name as the Catalog file with an extension "Previews.lrdata" see the attached snapshot.

Stray, random inappropriate pixels appear in images; no such problem in Int Explorer

Viewing images in, for example, Flickr photo streams, stray, random inappropriate pixels appear in images. Reload, the pixels change locations, usually close to the original misbegotten pixels' location. Sometimes multiple patches of wrongly displayed pixels, sometimes a single patch. No such anomaly appears under the same circumstances in Internet Explorer.

Thank you for your response. I'm not a person who can control much beyond the on-off switch on the computer. I'm pretty certain it's not a matter of physical heat. I have never seen the stray pixels in Photo Shop, which sometimes works the card pretty hard, I think. It's just viewers inside browsers and in the computer, Windows' native image viewer. Thanks again.

Not able to view images in gallery, when they are ...

Hi,
The file explorer was showing two default images folder and I was unable to delete one of them as I was unable to view images via gallery. Then i installed X-plore and deleted one of the images folder. Now, when I click images and select memory card as storage space, I cannot view them via gallery and view them only via X-plore. Please suggest how can I correct this issue.

Maybe I am stupid but if you delete the imagefolder, it will be gone. You can set your default imagefolder: goto Media-> Camera-> Settings-> Use Memory-> Card. You can also backup your card to PC, reformat the card in your phone, because it makes default maps for images, video, audio,.........and then copy your images back to the specific folder.

Firefox saves images to wrong location, but only when using "View Image"

For a while, I have had the problem above. I can save images just fine if I don't use the "view image" function first, with the images going to the intended folders.
Just to clarify, unlike some of similar problems I have seen described here, I am perfectly happy with Firefox remembering where I wish my pictures to go, on a site to site, or model to model (within the same site) basis.
The problem lies in that if I use the "view image" function, either in a new tab, or in the existing one, Firefox will often prompt me to save in a random folder where I have previously saved a picture. It will even suggest folders that I have not accessed for days.
Example:
I save image A to folder A, by right clicking the image and selecting "save image as".
I then (immediately after this), right click image A again, select "view image", then right click the resulting picture, and select "save image as". Now there is a fine chance that it want me to save the image to some other (previously used) image folder, even if I have not used the folder for a while, and even though I have just saved the same image to folder A.
This problem persists with multiple image file types, on multiple sites (I just tried it with someones avatar in this forum, and it wanted me to put it with my holiday pictures from 3 weeks ago).
I appreciate any assistance you can give - jinxie
FYI; If I "one-click" a file (like an mp4) to download it, it goes to my main / default download folder as normal.

This is because Firefox will track where you have saved images or other files from the website domain. Then whenever you select to save the file to your computer, Firefox will start the Save As wizard in the latest folder that you have used last time.
Here is an example:<br>
If you save an image from the domain <code>123.com</code> into the folder <code>123</code> it will save there. Then you save an image from the domain <code>456.com</code> to the folder <code>456</code>. Next you save a different image from the domain <code>123.com</code>. The save as wizard will assume that you want to save it with the other image from that domain and will automatically start in the <code>123</code> folder.<br>
This can make saving files faster and more organized, however not everyone wants this feature enabled.
To disable this feature you can do the following:
#Go to <code>about:config</code> in Firefox
#Locate the <code>browser.download.lastDir.savePerSite</code> string
#Change the value to <code>false</code>
This should fix the issue, but please report back if it doesn't.

Can not view images of Patents (i.e., D/359,691) on USPTO.gov Patent search, it tells me I need a plugin (Quicktime) which I updated already.
In the "Quick Search" I give terms & it compiles a list. I then go through to each doc and look to view the doc and associated drawings. I'm not sure what else to say at this juncture.

Why doesn't the "View image info" show how many frames are in animated gifs?

When I right click on an image, then click "View Image Info" it used to show how many frames were included in an animated gif. This stopped working in Firefox 4. Why is that?

I'm not too sure what I did but it works now.

What do I do to view images on CS5-64 when it will not open them?

The program will not open images, either directly or from Bridge. Using Win 7 on a Dell PC.

Strange, after rebooting, both Ph CS5 and Bridge are working again. Thanks for getting with me.

Is there a way to view image numbers in iPad photos, either of images taken with the iPad or of images copied into Photo (or camera roll) on the iPad?

Is there a way to view image numbers (metadata) on the iPad Photo app, distinguishing those taken with the internal camera from those downloaded from external camera or copied from an email?

sberman: My iMac is running iTunes 11.0.2 already. As well, the Photos tab in the iTunes window shows that "Sync Photos from" is un-checked. And in the box to the right of it is the greyed-out empty folder that I previously synced to in order to remove photos from the Camera Roll.
Ralph9430: I did a reset (Home + Sleep) earlier when I was trying everything I could think of. I have also re-synced a couple of times. No luck.
Thanks anyway. I was hoping someone out there would tell me they've experienced the same problems (non-functioning DELETE button, and persistent data in Photo Library), even if they haven't found a solution. Then I could assume it's a iOS 6 bug. All I can think of to do next is a full iPad restore.

When "allow pages to choose their own colors, instead of my selections above" is un-checked in the options menu, I am unable to see images on websites. How do I maintain having the box un-checked and still view images?

I recently decided to switch the colors around in Firefox. I work in a pretty dark environment and having dark colored text on white or bright backgrounds is rather difficult on my eyes in the dark.
I switched the background to a dark gray, the text to a light gray and both visited and unvisited links to a light blue. Along with these changes, I unchecked the "allow pages to choose their own colors, instead of my selections above" box.
After unchecking the box, I am no longer able to view images on many websites. The images all turn gray - as if Firefox has changed their image into part of the background. When I check the box, I am able to see images fine, however, the websites usually revert back to their bright backgrounds with dark text.
Any help and assistance with this is greatly appreciated!
Thank you!

How can I get to read the pixels in an image?

Please see details of my code below. What I am doing is trying to obtain the pixels for an image. there is an initial image of a certain size, which is then split into smaller portions.
The problem I'm getting is that pixels can not be read past the middle of the original image. I hope I have explained this so it can be understood. I have included the class that I am working on

When using private browsing to view image results in Safari 5.1.3, only the first two rows of results are visible, the following four or so rows display greyed out place holders, and the safe search button is inoperable. Suggestions?

When using private browsing to view image results in Safari 5.1.3, only the first two rows of results are visible, the following four or so rows display greyed out place holders, the remainder of the results page is blank, and the safe search button is inoperable. When I turn off private browsing and refresh the page, everything works again.
Anyone else having this problem?

I have got the same behaviour after the last Safari Update to 5.1.3. It seems that Safari now handles some scripts in a new way. If you debug the Google Website, you will see, that there is some Javascript Error, that seems to prevent to write into local cache. After some searching I wasn't able to finde a solution for this problem, other then disabling Javascript while private browsing to prevent the script loading. You then are able to use Google with the old layout. The option to disable JavaScript can be found in the Menu "Developer", wich has to be enabled in Safari in the options first.
In my opinion this is a bug that is now occuring, because Apple changed something in private browsing and that has to be fixed by Google now, to run again. Or we will have to wait for 5.1.4, as you can read online Apple will change and bugfix the javascript engine in that version, perhaps this fixes the problem as well. I hope so!
If anyone is in the developer program perhaps you could test this with the beta of 5.1.4 and tell us if it works.
