Cannot implicitly convert type 'System.Drawing.Image' to 'System.Drawing.Bitmap'`

img1 = new Bitmap(imgName[0]);
img2 = new Bitmap(imgName[1]);

img1 = (Bitmap) Image.FromFile(imgName[0]);
img2 = (Bitmap) Image.FromFile(imgName[1]);

As the error message says you cannot implicitly do this you need to explicitly cast it to Bitmap

Edit

Based on the comments below I would suggest either go with icktoofay's answer i.e. use the Bitmap constructor or if you can use the Image class directly instead of using Bitmap you can also go with that
