I use the simple web slide shows in PS to show clients the results of portrait sessions and also to show some of my work in progress. I want to use the File Name field they offer to show the File Name, but it seems that this only works if I go into each image's File Infoscreen and manually type in the information. I can't figure out howto batch process, making the file name (which I renamed in the File Browser area) the File Name... if that makes sense. I'm using Photoshop CS, by the way.
Try using the Batch Rename command and re-name the entire folder. You'll find the feature in the CS File Browser.
Choose File > Browse from thePhotoshop menu.
The File Browser window appears.
Choose Edit > Batch Rename from the File Browser menu.
The Batch Rename dialog box appears.
Choose a Destination for your newly re-named files.
In the File Naming: section, assign a logical name to your files. You can also add a series of serial numbers date perfect for sequential shoots. When you're satisfied, click OK.
I hope this helps.
