If the score is higher than the score of the current image, replace the Bitmaps bitmapData with the bitmapData of the loaded thumb 4. dispose the loaded thumb 5. repeat steps 2, 3 and 4 until all images from Flickr with the specified tag have been loaded and compared As I'm only replacing existing bitmapData, and then disposing the loaded thumb, the memory usage should never expand so you can leave it for an hour and it won't (/shouldn't) crash your browser. I hope that helps explain how it works and thanks for the positive comment. Hey Kaho, the programming flow goes like this:

As I’m only replacing existing bitmapData, and then disposing the loaded thumb, the memory usage should never expand so you can leave it for an hour and it won’t (/shouldn’t) crash your browser.

I hope that helps explain how it works and thanks for the positive comment.

We're all going to expect something even more impressive from you now! Wow, pretty impressive. We’re all going to expect something even more impressive from you now!

Basically as long as there are images available with the selected search tag it will just keep going. Memory usage shouldn't increase as the initial image is made up of BitmapData, and all that happens when a successfully match is made is the BitmapData is changed to that of the loaded Flickr thumbnail. If you right click on the app and select 'Show Profiler' from the menu, a graph will appear showing exactly whats happening with memory usage etc (one thing to note though, if you have other Flash apps open in the same browser their memory usage will also be displayed) You can grab that profiler from <a href="http://www.lostinactionscript.com/blog/index.php/2008/10/06/as3-swf-profiler/" target="_blank" rel="nofollow">here</a> - very useful tool, I use it on everything I build!

how does memory versus time look?
does it eventually go “right, this is good enough, let’s stop” ?
