+=====LatexSlideshow=====
 I found myself in a situation recently, where somebody wanted to create a Powerpoint slideshow for a hundred or so photos, all with the same header and footer. I thought it might be a lot easier to produce the file using Latex, and indeed it was. This is what I did.
 The steps shown here include resizing and renaming the photos first.

-==Resize photos==
+===== Resize photos =====
-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.

-==Rename files sequentially==
+===== Rename files sequentially =====
-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:

 You should now have all your images as 1.jpg, 2.jpg and so on.
