Hello, I just wanted to post simple code snippet how to add custom file restriction. For example you can allow to select images with 3:4 aspect ratio only: Code:<script language="javascript" src="iuembed.js"></script>
<script language="javascript">
function ImageUploader_UploadFileCountChange(){
var imageUploader=getImageUploader("ImageUploader");
for (i=imageUploader.UploadItems.Count; i>=1; i--){
var uploadItem = imageUploader.UploadItems.Item( i)
if (uploadItem.Height/uploadItem.Width!=0.75){
alert(uploadItem.FileName + " doesn't have 3:4 ratio.");
imageUploader.UploadItems.Remove(i);
}
}
}
</script>
<script language="javascript">
var iu = new ImageUploaderWriter("ImageUploader", 770, 500);
//For ActiveX control we specify full path for CAB file
iu.activeXControlCodeBase = "./ImageUploader3.cab";
iu.activeXControlVersion = "3,5,204,0";
//For Java applet we specify only directory with JAR files
iu.javaAppletCodeBase = "./";
iu.javaAppletCached = true;
iu.javaAppletVersion = "1.1.81.0";
iu.addParam("Layout","TwoPanes");
iu.addParam("Action","Upload.aspx")
iu.addEventListener("UploadFileCountChange", "ImageUploader_UploadFileCountChange");
iu.writeHtml();
</script>
Best regards, Fedor Skvortsov
