When you open a photo album on your phone, you’re likely to see thumbnail icons that look different depending on the device you’re using. On some devices, like the iPhone, they may show a small image of the photo while others may show a full-sized image. If you’re having trouble finding an image that looks right on your device, there are a few things you can do to fix it. First, make sure that your device is set up properly with thumbnail icons. If not, try changing your wallpaper or setting up an app to have thumbnail icons. If you still can’t find the right image, there are other ways to view photos on your phone. For example, if you have an Android phone and don’t have thumbnail icons in your photo library, you can use Google Photos or iCloud Photo Library to view photos.


Here’s a good example of the problem… almost all of the folders under my picture library are showing the Windows Media Player icon. How does that even happen? Sometimes they start showing the right image, but then they’ll randomly revert back, and forget about using one of the other views.

The problem is that all of the preview thumbnail images used in the icons are stored in a cache file, which sometimes goes all wacky and gets corrupted, and requires some cleanup.

Fix the Problem with Disk Cleanup

To fix the problem, simply open up Disk Cleanup by typing “disk cleanup” into the start menu search, or find it under the accessories area. You can run a full disk cleanup if you want, but if you just want to quickly fix the problem, scroll down until you see Thumbnails and make sure that one is checked.

You’ll want to click the “Clean up system files” button, wait for it to finish, and then probably log off and back on.

Everything should be looking good now. Did it solve the problem for you?

Note that all the screenshots are from Windows 7, but we’ve used the same technique on Windows Vista as well.
