Hey all, I am about to embark on reprocessing approx 100k user photos with new dimensions that a site redesign has called for. We used AttachmentFu and have stored the originals in case this ever came up. I don’t see anything built directly in AttachmenFu and was planning to write some rake tasks to do this myself, but figured it was worth a shot to find out if anybody else had to do this and wanted to share any pointers/code. 🙂 Thanks in advance!

So, now, I’m really happy to have the chance to pay you back 🙂 We faced the same situation as you (though with fewer than 100K images, I must say), and I wrote code to rehash all the existing images to the new thumbnail sizes. You’ll find it at [http://pastie.org/298645](http://pastie.org/298645). In our case, we were using S3 for image storage, and I had to insert the sleep at line 12 to avoid freaking S3 out, but, if you’re using local file storage, it shouldn’t be necessary. Hope that helps- Danny [http://rejaw.com/help/about#danny](http://rejaw.com/help/about#danny) ---

Just tested it out and it works perfectly. Now to get ready to start reprocessing 100x x 7 variants… 700k photos! Thanks again! Cheers, Robby – Robby R.
