If the file contains a "known" image type (.JPG, .BMP, .PNG, ...) then it's easy:
Dim im As Image = Image.FromFile(pathToFile)
If it doesn't, but contains a (for example) proprietary graphics format that then framework doesn't support, then you will have to find or write a converter to read the file info and generate an Image from it. We can;t help with that: we have no access to your file data and do not know what it contains.
If you do write your own loader, then it would probably be worth writing an article on the process and publishing it here:
