Batch renaming jpeg files

[Sam25]

I have tons of photographs (jpeg) in 3 different folders. I wanted to know if there's an open-source software for batch renaming the jpeg files?

TIA

Irfanview does batch renaming.

Thanks, Thanks Thanks! Gotta love IrfanView... I knew it does Batch resizing but I tried Batch Renaming now and it worked flawlessly. Awesome!

It sounds like you found what you needed, but here's a free, multi-purpose renamer which I've been using for years:

Bulk Rename Utility

the file renamer i've been using (for any extensions) since 2007 is Metamorphose.
it's free. XnView, (IrfanView competitior) also does batch renaming, resizing and conversions.

You can also do it within FastStone Image Viewer. Some serious batch capability with FSIV. I like it better than Irfanview.
