- You start Windows Photo Gallery
- You select File, then choose Import From Camera or Scanner.
- You then import a very high-resolution image. For example, you use a high-resolution scanner to scan a full-page document at a resolution of 1200 dpi.
In this scenario, Windows Photo Gallery will fail to display the image, and will display the following message:
For example, if you scan a full 8.5x11" page using a resolution of 1200 dpi, the resulting image file will be extremely large (approximately 136 megapixels). This exceeds the default size limit for Windows Photo Gallery.
When scanning an image, reduce the size of the image by scanning a smaller area (not a full page), or by using a lower resolution, such as 600 dpi or less. This will allow Windows Photo Gallery to open the scanned image successfully.
Alternately, you can override Windows Photo Gallery's image size limit by editing the registry:
- Click Start, type regeditin the Start Search box, and then click regedit.exe in the Programs list. If you are prompted for an administrator password or for confirmation, type a valid password, or click Continue.
- Locate and then click the following subkey in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows Photo Gallery\Viewer
- Click Edit, click New, and then click DWORD (32-bit) Value.
- Type MaximumFrameSizeMegapixels for the value name, and then press ENTER.
- Double-click the MaximumFrameSizeMegapixels value, click Decimal, enter a new value in the Value data box, and then click OK.
- Exit Registry Editor.
- Restart Windows Photo Gallery.
Note: Entering a value of 0 will disable the image size limit. However, this is not recommended, because if Windows Photo Gallery then attempts to open an extremely large or corrupt file, it could potentially result in a hang or crash.
