I am having an Web Application(ASP.NET MVC, C#), in which I have a functionality of uploading an excel which contains image path. So I need to know can I access the image files from the application?
PS: Images and Excel will be in the user system.
You could make the users send the real images within the file instead of sending only the paths. This would potentially generate a huge file to upload, but I don't know you application.
If image is at user location then there is no way you can access it (how insecure it would be if any website can access your image file in your system)
So your will need user to upload image as well inorder to use it

I am trying to build a bulk upload functionality on an ASP .NET page. this is required to upload questions and answers in a SQL table. There can be images as well in the question and the answers. For those images, the path to image can be specified.
Is it possible to copy the images from end user's machine to the server and then move these images into the SQL database?
"Is it possible to copy the images from end user's machine to the

Not unless you provide a file input control explicitly on the page and the user puts the necessary file(s) into that control and they get uploaded along with your other data.
Your server does not have access to the user's machine. In fact it almost certainly doesn't even know exactly which machine the request came from. It certainly doesn't have access to any of its disk drives, unless the machine has its own specific public IP address and appallingly lax firewall and security settings.
In fact even your webpage, when it's rendered in the user's browser - which is on their machine - doesn't have access to the disk (think of the implications if a webpage could randomly read files from your disk!) except via a file upload control where the user has to specifically choose which files to send to the server.

I am creating a website in which I need to find out the path of the downloaded files.For instance if there is an image Image1.jpeg, downloaded and saved somewhere in the system.Is there a way through which we can find out the path of that image?
If you mean: how to retrieve an uploaded image, the answer is: not possible. An uploaded image (or just any file) consists of a name an a list of bytes. You have to save it yourself.
If you are asking about downloaded files on the client, well, they are on the client, so outside of your control.

I want to fetch images from a Drupal DB to a C# program.
In Drupal DB the image path is:
"public://yourimage.jpg"
However, this is not a usable URI for C#.
How can I get images from Drupal to C# in a secure way?
If you are going to fetch the images from a database, the URL is not important, what you need to know is if the image is in the database and in wich tabel, and if images are stores in file system, in which table is the path. Then, use plain Ado.Net to get those images.
If instead you want to fetch images from the web, then you'll need to build some kind of grabber. Maybe CsQuery project can help you in that..

I want to ask how can I copy files from PC to MAC using C#. Also my application will create new folder when needed and copy / move files in them
By which technology you want to move files ?
1- Over the network ? using Directory access protocols ?
2- Through Web ?
Each has different aspects. as for network you just need to have access to mac on windows computer and tell them path. using **SYSTEM.IO** name space you can easily copy files from one directory[Windows] to other[MAC] using their path. Window will take care of permissions but be sure the user which you are using to access has write permission to folder where you are copying files.
Through web you might need to implement web programming to read and write each file you post.
