Yes this is possible if you want to process all odd numbered files.
This example will prompt for the input folder and write the output files to a folder called processed off the input folder.
N.B. You need to change the line:-
[code]doAction("ActionName","ActionSet");[/code]
To reflect the actual name of your action!
[code]
#target photoshop;
app.bringToFront();
main();
function main(){
var inputFolder= Folder.selectDialog ("Please select folder to process");
if(inputFolder == null) return;
var outputFolder = Folder(inputFolder + "/processed");
if(!outputFolder.exists) outputFolder.create();
var filelist = inputFolder.getFiles("*.jpg");
for (var x in filelist){
var Name = filelist[x].name.replace(/\.[^\.]+$/, '');
var num = Name.match(/(\d+)[^\d]*$/)[1];
if(Number(num)%2){
//odd number
app.open(filelist[x]);
//modify the line below to show your actionname and action set
//this is your action for the watermark
doAction("ActionName","ActionSet");
var saveFile = File(outputFolder + "/" + filelist[x].name);
SaveJPEG(saveFile,8);
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}
}
};
function SaveJPEG(saveFile, jpegQuality){
jpgSaveOptions = new JPEGSaveOptions();
jpgSaveOptions.embedColorProfile = true;
jpgSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
jpgSaveOptions.matte = MatteType.NONE;
jpgSaveOptions.quality = jpegQuality;
activeDocument.saveAs(saveFile, jpgSaveOptions, true,Extension.LOWERCASE);
};
[/code]
