select the icon of a file of that type and choose File -> Get Info. In the Info window, expand the Open With section if necessary, and select your preferred application from the pop-up menu. Click the Change All button and then click Continue in the confirming dialog box. Now this file type will always open in the application you prefer.
Thanks, but my issue is not about opening image files, but about how the preview icons display within an image folder.
Most photo files display an image preview as thumbnail icon, but some image files (after Saved For Web) only show up as generic JPG icons instead of the preview thumb.
Frustrating, sinceoften times I need to search for specific images within large folders and icon view is usually the best view mode for a fast overview.
Adobe claims it's a Mac issue, but haven't found a workaround so far.
Update: still struggling with the generic jpg icon/thumbnail issue.
I trashed the Finder preference file (com.apple.finder.plist) & relaunched Finder - did not fix.
I did Get Info on an indivual image file and deleted the icon in the top left on the Info window
- this fixes the issue (image thumbnail shows up in folder), but there's no way to apply this workaround to hundreds of generic jpg files!
Frustrating, since browsing large image folders in icon preview view is the fastest workflow for me.
This is still an ongoing & rather frustrating problem, especially when browsing large volume image folders:
image files in most folders will only display as generic jpg icons in all four folder preview settings [icon, list, column or cover flow]
Trashing the Finder preference file did NOT work, neither did relaunching the Finder.
Two workarounds DO help, but are just too cumbersome to apply on a daily basis:
A. Highlight a single icon > Get Info > delete generic jpg icon in the info window > close window
B. Open folder > Command-F to bring up search window > select name of image folder > choose "Is Image" in the Kind option bar > all images now display in the folder window
Also, I noticed there are four additional Finder preference files - each with a different seven digit letter/number combination after the file name "com.apple.finder.plist"
Would it be safe to delete all these files ... or are these files maybe creating the issue?
Are you still using PS CS5? There's a known issue with PS CS6 not writing icons correctly (see the Photoshop user forum) but none that I know of with CS5.
You might want to post in the Adobe Photoshop User forum -> http://forums.adobe.com/community/photoshop.
Had the same problem, tried repairing permissions, flushing caches, trashing the plist.
Here is what worked for me.
The slow way
- open the file in preview
- select the image (Cmd-a)
- copy the image (Cmd-c)
- Back to Finder with the file selected
- Get information (Cmd-i)
- Select the image well (the littile icon at the top of the inspector window)
- Paste (cmd-v)
- Close info window and preview
- Open Automator
- Choose to create a service
- Runs on image files, in Finder
- In the Photos Library find "Add thumbnail Icon to Image Files" and drag it over
- Now you can select as many png files as you like and change them all
