image dimensions

[rashad kabbara]

is there a way to determine if an uploaded file is an image? is it possible to automatically check the extension of a file and determine (in client side) that the file is an image?
after determining if a file is an image, is it possible to determine (client side) the dimensions of the uploaded image

Hi,

You can use the validateExtensions() client-side method to validate file extensions on the client. Checkout the folowing link to know more on this.
Validating using an ASP.NET validator

Also the following link illustrates how to perform checking filesize on client.
