Bulk batch image resize

I have created a new site and? most of the images that I want to programmatically import are throwing back an error because they are too big. I need to ensure that all of the images in a folder (and series of subfolders) do not exceed a particular size (e.g. 1024px x 768px) or weight (e.g. 2Mb). I have found programs that will do this for an individual image or for everything in one folder? but I need this? for all of the images contained within the subfolders too. To preserve the originals I would like to be able to choose a destination folder. All of the? appropriately sized images (even if they didn't? need to be manipulates) should be moved into this new folder in the preserved folder structure. Ideally I would like to be able to set the parameter that the software is working towards (e.g. a maximum weight or max height or max width). e.g. ORIGINAL: 2009 ? ? ? ? //January ? ? ? ? ? ? ? ? ? ? ? ? //[login to view URL] ? ? ? ? ? ? ? ? ? ? ? ? //[login to view URL] ? ? ? ? ? ? ? ? ? ? ? ? //Birthday ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? //[login to view URL] ? ? ? ? //Feb ? ? ? ? ? ? ? ? ? ? ? ? //[login to view URL] ? ? ? ? ? ? ? ? ? ? ? ? //[login to view URL] AFTER MANIPULATION: 2009_resized ? ? ? ? //January ? ? ? ? ? ? ? ? ? ? ? ? //[login to view URL] ? ? ? ? ? ? ? ? ? ? ? ? //[login to view URL] ? ? ? ? ? ? ? ? ? ? ? ? //Birthday ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? //[login to view URL] ? ? ? ? //Feb ? ? ? ? ? ? ? ? ? ? ? ? //[login to view URL] ? ? ? ? ? ? ? ? ? ? ? ? //[login to view URL] ## Deliverables If there is any software out there that already does this don't feel obliged to put in a bid - you could always just tell me where to get it! Speed is important in this!
