Displaying Embedded Thumbnails In Digital Camera Images; Generating Thumbnails - Ulead PHOTO EXPLORER 8.5 User Manual

Storing cache files in their respective folders allows you to include them with media
files when burning media files on CDs. When you browse a CD, Photo Explorer will
load thumbnails from the cache files on CD.

Displaying embedded thumbnails in digital camera images

Since many digital cameras can now automatically create thumbnails when taking
photos, you can customize Photo Explorer to just get the thumbnails from the JPEG
(Exif) image files instead of generating them.
For such images, select the Use thumbnail from JPEG (Exif) file option in the
Preferences dialog box under the Camera and Exif category. This will give a considerable
improvement in thumbnail display speed. However, thumbnails created by cameras are
fixed in size (160x120) and cannot be further enlarged. Also, the display quality of the
thumbnails may not be as good.

Generating thumbnails

If you have modified images or other media files outside of Photo Explorer, your changes
may not immediately be reflected in the cache files. There may also be unused
thumbnails still remaining in the cache files even after their corresponding files have
already been deleted.
To update thumbnails in the cache files or to clean up cache files by removing
thumbnails for non-existing files, manually regenerate thumbnails for the respective
folders. Photo Explorer provides two ways of regenerating thumbnails:
• Select View: Regenerate Thumbnails
to recreate thumbnails for files in the
current folder level only.
• Select View: Scan Tree to recreate
thumbnails for files in the current
folder level and all its underlying
subfolders. (On the contrary, to delete
thumbnails for files in a directory tree,
select View: Remove Thumbnails.)
