 I used the Imagemagick <tt>mogrify</tt> command to bulk resize all the images. This command resizes all images to a maximum size of 1280x1024, but does not resize them if they are already smaller than that.

 The following Perl script renames all the files sequentially. This makes it easier to include them in the Latex script. See [http://stackoverflow.com/questions/3211595/renaming-files-in-a-folder-to-sequential-numbers this Stackoverflow question] for more details.

 Save the above script and run:
- ./rename.pl images
+  ./rename.pl images
 You should now have all your images as 1.jpg, 2.jpg and so on.

 Run the script. <tt>xelatex</tt> is used so that fonts can be used:
- xelatex slides.tex
+  xelatex slides.tex
 This will produce <tt>slides.pdf</tt>. This file can be opened with Adobe Acrobat and shown in full screen to see the slideshow with transitions. As much as I dislike the proprietary Adobe viewer, it does show the slideshow well, which not many other PDF viewers seem to support.
