Saving multiple images at one time to a different folder

Does this help?

/* save open documents to location */ /* 2013, use it at your own risk */ if (app.documents.length > 0) {           var myDocument = app.activeDocument; /* create dialog */           var dlg = new Window('dialog', "select files", [500,300,830,565]); /*create list of open files, thanks to paul r */ dlg.fileList = dlg.add('listbox', [15,15,315,220], 'field', {multiselect: true}); /* populate the list with the open files’ names */ for (var o = 0; o < app.documents.length; o++) {           dlg.fileList.add ("item", app.documents.name);           dlg.fileList.items.selected = true           }; /* buttons for ok, and cancel */           dlg.buildBtn = dlg.add('button', [13,230,160,255], 'OK', {name:'ok'});           dlg.cancelBtn = dlg.add('button', [170,230,317,255], 'Cancel', {name:'cancel'});           dlg.center(); /* show the window */           var myReturn = dlg.show ();           if (myReturn == true) { /* get the selcted ones */           var theSelected = new Array;           for (var p = 0; p < dlg.fileList.items.length; p++) {                     if (dlg.fileList.items .selected == true) {                               theSelected = theSelected.concat(app.documents )                               }                     }; /* folder selection */           var theFolder = Folder.selectDialog("select a folder");           if (theFolder) {                     var thePath = theFolder.fullName;                     psdOpts = new PhotoshopSaveOptions();                     psdOpts.embedColorProfile = true;                     psdOpts.alphaChannels = true;                     psdOpts.layers = true;                     psdOpts.spotColors = true; /* save the psds */                     for (var m = 0; m < theSelected.length; m++) {                               app.activeDocument = theSelected;                               var theDoc = app.activeDocument;                               try {var basename = theDoc.name.match(/(.*)\.[^\.]+$/)[1]}                               catch (e) {var basename = theDoc.name};                               if (File(thePath+'/'+basename+".psd").exists == false) {                                         theDoc.saveAs((new File(thePath+'/'+basename+".psd")),psdOpts,false);   theDoc.close()                                         }                               else {alert ("a file named "+basename+".psd"+" already exists in that folder")}                               }                     }           } };

What version of Photoshop are you using? Newer versions have a preference for 'Save as to original folder'. With that preference off you will not have to keep choosing the new folder.
