ThumbsUp is a simple, drag & drop based utility that creates thumbnails for a bunch of pictures and supports all image formats of Mac OS X and Quicktime (including PDF documents).

In addition size, antialiasing and quality are configurable. Note that this utility is not intended to be an HTML thumbnail gallery generator.

Here are some key features of "ThumbsUp":

· Extension inserted before (Prefix) or after (Suffix) the name of thumbnail files or name of subfolder where the new thumbnail files are stored
· Image format of thumbnails (TIFF, JPEG, BMP, GIF, PNG or JPEG 2000)
· Note: JPEG 2000 requires Mac OS X 10.4.x.
· Quit when done (only if the application is launched by a drag & drop operation, otherwise the application displays the preferences panel)
· Create thumbnails, thumbnails with icons or only icons for the original files
· Maximal width and height of thumbnail images or scale images by percentage
· Note: If you set scaling to 100%, you're able to use ThumbsUp to convert
· PDF screenshots easily to other image formats
· JPEG compression (the higher the quality is, the bigger the resulting files are)
· No, low or high antialiasing of scaled thumbnails
Sharpen:
· Light, medium, strong or no sharpening of thumbnails.

Requirements:

· QuickTime 6 or later
