A Quick way to resize images in batches could be find that Preview has that functionality. Open the whole batch of images in Preview; the images will all open in the same window with thumbnails visible in the sidebar.
Select all of the thumbnails in the sidebar (with Command-A, or click the first and then click the last while holding Shift). Next, from the Tools menu, choose Adjust Size. You’ll be presented with a dialog containing options to resize to all the common 4:3 and 16:9 screen sizes, as well as the option to define custom dimensions. Images are scaled proportionately and resampled by default.
Save the resized images, and you’re done!
Preview will prompt you to save any changes if you attempt to close the window.
You can also use sips on the command line:
sips -Z 1024 *.jpg
will resample to a max of 1024 px for the long edge.
Note that sips rewrites images in place, so you should do this on a copy if you care.

One of the great features in Adobe Acrobat Pro is the ability to annotate (comment, markup, circle, highlight) PDF documents and images like JPEGs, PNGs, etc. Although, there are many other features (like creating forms) in Acrobat that are useful for PDFs, it’s not really fair to compare it to Preview. Nonetheless, for those who don’t have Acrobat Pro or don’t want to buy it, Preview has become quite powerful especially with the new Annotate toolbar added in Snow Leopard.
- Open up a PDF or IMAGE on your Mac with Preview.
- Click on the Annotate button in Preview, located next to the Select button on the top.
- Now, you should notice a toolbar appear on the bottom on Preview.
- Use this Annotation toolbar to highlight text, add circles or squares around important text, add hyperlinks, add text, or add colorful arrows.
- Once you’re done making any changes to the file, make sure to save it.

Quick Look has a hidden feature that is not enabled by default, and can only be enabled through Terminal. Essentially, when ‘X-Ray mode’ is turned on, Quick Looking a folder will show, in a way, the contents of the folder.
Instead of just seeing the regular folder icon in Quick Look, the folder icon will be semi-transparent, with previews of the folder’s contents visible in the Quick Look window, as seen in the image at right. What’s more, the preview images will rotate automatically, moving through each item in the folder (click the image to see a movie of the animation).
To turn this on, quit the Finder (using Activity Monitor, Terminal, etc.), then open Terminal and enter this command:
$ defaults write com.apple.finder QLEnableXRayFolders 1
Relaunch the Finder, and enjoy the new folder X-Ray mode in Quick Look. If you ever want to disable it again, quit the Finder, then repeat the above Terminal command, but change the 1 to a 0.

In Snow Leopard’s PDF Preview,
if you click Control – or Right-click on a PDF preview and change the display option (e.g. from Single Page Continuous to Two Pages), this setting does not stick between launches. The next time you open a PDF, Preview reverts back to the original display setting.
However, if you change the display setting from the menu (View » PDF Display) the setting does stick, and becomes the new default for viewing PDFs in Preview.
