Hey;
What is any easy to use program to generate thumbnails from a 'full
sized'
image?
I have tried many programs found using apt-cache search BUT either I
am to
stoopid to figure them out or they really don't do what I want.
Fore xample:
convert image.JPG -resize 10% images.jpg complains.
To create thumbnails use the -thumbnail option of convert. This option
preserves the aspect ratio of the picture. So you need to specify just
the width or height of your thumbnail.
Sample commands look like
convert -thumbnail 160 original.jpg thumbnail.jpg
convert -thumbnail x160 original.jpg thumbnail.jpg
The first one creates the thumbnail whose width is 160 pixels. The
second one creates a thumbnail whose height is 160 pixels.

The -thumbnail option does not appear to be needed. I just use the
following command:
convert original.jpg -resize 130x130 thumbnail.jpg
This gives me a thumbnail with the largest dimension being 130 and the
other dimension proportionally smaller. This way, I know that the image
will fit in a 130x130px box regardless of its original size and
orientation. My 400x600 original picture is resized to 87x130.
