Batch process in Photoshop

I´ve trying to batch my pictures in Photoshop but the thing is that it transform them in the extention .psd
I know that I coould use the Web Photo Gallery for transform let them in jpg extention, but the thing is that I would like also to change the file names of them which I can only do in the batch process.
I also know that I could do in times: first the size in the W.Photo Gallery and after take the pictures and change their names in the batch process.
What I would like to know is if I can fine a plugin or something like that where I could do everything in one time.
Thanks a lot

I'm not totally sure what you are trying to do.

With a batch process all you need to do is create an action that does what you need it to do. SO if you need to resize a bunch of images, then save them at 60% .jpg, create an action that does this. Once you do that, then select the batch process and set a start folder, end folder, which action to batch with, and what naming convention you need.

Hi Marble,
That´s works very much OK. Thanks very much for your help.
