I just thing to open only horizontal/vertical image from a folder

[akmia51]

var fol=Folder.selectDialog('Select a folder With Mixed Image horizontal And vertical Image');
function horizontal(fol){
    var files = fol.getFiles(  //get only horizontal image---------
        );
        for ( i = 0; i < files.length; i++) {
            open(i);
        }

}
function vertical(fol){
    var files = fol.getFiles(  //get only vertical image---------
        );
        for ( i = 0; i < files.length; i++) {
            open(i);
        }

}

i don't know how can I do id

You would to get all the Image files names then filter the file list be processing the file meta data.  Even the file filtering that can be done on windows is only relative to file types not image attributes. getfiles gets you a list of file names. On Mac you even have to code a filter to filter file types.

function gF(v) {
	if (!ExternalObject.AdobeXMPScript)
		ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript'),
		gP = function(v) {return xmp.getProperty(XMPConst.NS_EXIF, 'Pixel' + v + 'Dimension')}
	xmp = new XMPFile(v.fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_READ).getXMP()
	return eval("gP('X') " + lessthanorgreaterthancharacterassignedearlier + " gP('Y')")
}

lessthanorgreaterthancharacterassignedearlier = ['<', '>'][0] 
fls = Folder.selectDialog().getFiles(gF); while(fls.length) open(fls.shift())

[JJMack]

Had to add a try catch to ignore errors that happen in the gF function when the selected folder has folders and perhaps some none image files.

[Kukurykus]

try...catch statement is also necessary, because ExternalObject is not always reliable.

[akmia51]

can you just check it bkc its not working at all 

[Kukurykus]

Now it's set to open vertical images. Change 0 to 1 to open only horizontal ones.

[akmia51]

I tried but not opened any images

[Kukurykus]

For me all works. Attach some of your jpgs for me so I'll try them on my side.

Some files do not contain metadata at all, for example PNG, BMP and others.

[Kukurykus]

I use this script for .jpg format, for others I sometimes read binaries.

test image
check this link i have attached images and a screen recording video also

[Kukurykus · Accepted solution]

If normally the orienation of your images is horizontal then use:

function gF(v) {
	if (!ExternalObject.AdobeXMPScript)
		ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript')
	xmp = new XMPFile(v.fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_READ).getXMP()
	return /1|3/.test(xmp.getProperty(XMPConst.NS_TIFF, 'Orientation'))	//	or use 6|8
}

fls = Folder.selectDialog().getFiles(gF); while(fls.length) open(fls.shift())

[akmia51]

its working but some time its doing misteks like if the image dont have XMP data
like the attached image
i just think like this now

var files = File.openDialog ("Select mixed Image", "", true);
var potrait=[]
var hor=[]


for(f=0;f<files.length;f++){
    if(check (files[f])){potrait.push (files[f])}else{hor.push (files[f])}
    }
function check (fil){

// it should not check XMP and it should not  open file in photoshop
    
if(fil is  potrait ){
return true;

}else {return false;}
    
    }
// then we can get all potrait and hor.. file separet

[Kukurykus]

If the images with no XMP are landscape too then instead of appropriate line use:

return !(ornttn = xmp.getProperty(XMPConst.NS_TIFF, 'Orientation')) || /1|3/.test(ornttn)
