Hi!

For a personal project, I have undertaken the idea of learning how to produce a program that grabs a set number of random images from specified servers (and from random directories that may not be locked out for the public.) After it does that, I want it to output the <img> tags of each picture it found, on a plain white HTML page, as the final output.

It seems simple enough, but I would like feedback on my programming flow chart, since that way I would be able to work on the actual code part later without having to redo it over and over. (Getting it correct in less retries.)

Here is the flow chart I currently have:
  1. Initialize variables
  2. start a loop using the number of servers you chose to perform this operation on as the max number of times to execute loop.
  3. Open connection with remote server.
  4. Find a random available directory.
  5. Search for any .gifs, .jpgs, or .pngs to possibly grab.
  6. Randomly choose one, save that link to somewhere for use at the end of the script.
  7. Close connection with current remote server.
  8. Go back to #2 if there are more specified times to do this, else, keep going.
  9. Exit program safely.
  10. Output a plain .html file showing the results of what you had it find.


One of the reasons this project became something that is interesting to me is: at a MacHack conference one year, I heard about this program that did essentially the same thing as what I want to do, however it grabbed random images off of an airport network. Anyways, I wanted to be able to write something similar in Perl.

If there is something I am totally missing in that flow chart for what I need this simple program to do, please let me know about it. It's just the flow chart I have come up with, and hasn't been refined/added to yet by anyone other than me. I would appreciate a different perspective on it.

Thanks!
