Every so often I find that my preview thumbnails through my Mac finder disappear. They don’t disappear entirely, they just stop displaying the preview of the file and show only the generic jpeg icon. It’s a fairly bothersome problem, especially when so much of my work is visual. Fortunately, there’s an easy fix for this, however the fix isn’t always easy to locate when searching the web for answers. So, I thought I’d share it here for you (and for me the next time I need it.)

1. Open to the Preferences folder of your home directory
   (your home > library > preferences)
2. Delete com.apple.finder.plist
3. Right click on Finder icon and select Relaunch. (You can also open the force quit window and relaunch Finder.)

Note: You may see some previews and not others.. if it seems that your Photoshop file preview thumbnails are fine, this could be because Photoshop saves a preview intentionally where as other applications are showing previews differently.

2 other things to try to fix missing file preview thumbnails:

• Make sure “Show preview” options is selected. If the problem is only affecting a specific folder, look at your folder’s “View Options” (finder > view > show view options) then select “show icon preview. Close the options window.  This problem could be due to a corruption in the “.DS_Store” file that contains these settings

• Change the default application associate with your file/s. To render certain file types, the Finder uses “Preview” by default. If you have changed to a third-party application, it is possible the switch is causing problems with your previews. You can fix this by selecting one of your mis-displaying files and choosing the Preview application as the default handler.
  1. Right click the file
  2. Get info
  3. Under “open with” choose the application “Preview”
  4. Optionally you can then choose “change all” – however I wouldn’t recommend this unless you’re certain you’d like all similar files to open with Preview. Otherwise you’ll end up with another bothersome problem.. everythin opening in Preview when you’d rather it open elsewhere.

There is a heck of a lot of noise out there these days about using Twitter and tweets and following people. There are a number of uses for Twitter as well as a wide array of resources, tools and information all geared towards twitter accounts. If you found this article because of a link posted to Twitter, you already know most, if not all, of the following information.

If you haven’t yet signed up nor used a Twitter account – ever, here’s a quick guide to help you get going. The most important aspect of using Twitter is…
Having a Twitter account. You need one. We’ll talk about tools and techniques another day.

1. sign up go to twitter.com to get started

Your name – can be changed later
Your Username – CAN NOT be changed later. make it something meaningful to your or your business. Example, my twitter Username is “jgoode”.
Password – you know how this works
Email – use an email account you actually read from time to time. This email address is not publicly viewable

There are indicators to the right of each of these fields to let you know if the choices you’ve made will be accepted or not.

2. Sign up page 2 – skip this unless you already know of people you’d like to add from other accounts you may have

3. Sign up page 3 – again, skip this – unless, of course, you are feeling daring and what to follow complete strangers from the beginning

4. Set up your profile – from your account page, click on “settings” (the “profile” link is to view your profile only)

You can adjust any of the information on your profile page – but please do not change your user name unless you want all of your followers to think you’ve disappeared. Your username is how people find you and interact with you.

It’s a good idea to, at a minimum, include a profile picture and  “bio”.
A bio should be some kind of short message about you or your company – make it interesting and memorable.

5. Next add your profile picture. Click on “Picture” to upload a profile image. Square images seem to work best. Your image does NOT, and should not, be the tiny size you see. Upload an image that is a bit larger – at least 200px x 200px. The reason for this is, viewers can click on your profile image to see a larger view. With this in mind, make sure your image represents you or your business.

NOW you are ready to follow friends!

You can “tweet” without “followers” but really that’s more like talking to yourself. To gain followers you need to tell people you have a Twitter account (remember to tell them your user name) or you can follow other people and many times they will follow you back.

When ever you see the @ followed by a name or word, when people are talking about twitter, that name or word is the person’s Twitter account username.
Example my twitter is @jgoode. My Twitter account can be viewed by going to twitter.com/jgoode.

So, if you have friends that have told you (outside of Twitter), “hey follow me, I’m @so-and-so”, then you would simple go to twitter.com/so-and-so (this account doesn’t exist by the way.).

Once you’ve navigated to the person’s twitter page, simply click on “follow”. This will now allow you to view what this person says, in your own account window.

Note: Sometimes You’l find people you want to follow have their account set to “private”. In this case you need to request to follow them. Once they approve your request, you’l begin to see their “tweets” on your account page as well.

NOW – Your ready to Tweet!
“Tweeting” is just a matter of sharing short thoughts, ideas or comments. You can say whatever you like withing 140 characters. Anyone who is “following” you can then read what you have to say.

You’re ready! Get going and get Tweeting!

Please feel free to follow me and send me a message letting me know you read my tutorial. To send me a message specifically, simply type your message beginning with @jgoode – example, you could type the message “@jgoode hey I’m following you now because I read your quick guide!”
