Hi,
I'm not sure about using those thumbnails, but I usually make
thumbnails using the mogrify command (part of ImageMagik):
mogrify -geometry 120x100 *.jpg
will resize the images to 120 by 100 while keeping the aspect ratio.
If you want to actually force 120x100:
mogrify -geometry 120x100! *.jpg
If you have some images smaller than your thumbnail size, and don't
want them to be made larger:
mogrify -geometry 120x100> *.jpg
would resize a 640x480 but not a 100x100.
Be warned though, mogrify changes the files you're working on! What
I do is cp all the files I want to make thumbnails of to filenames
like "origpicname_t.jpg" and then use "*_t.jpg" with the mogrify
command. Seems involved, but if you write a little script that uses
'basename' and a few other goodies, it really simplifies it. If your
interested, but not familiar with shell scripting, write me and I'll
see what I can do. :)
Course, if you've got a dir full of pictures that you want to make
thumbnails of, you could make a thumbnails directory with copies of
all those images and then just mogrify * in the thumbnail directory.
Hope this helps,
Ben Logan
