We can store the file path of the image inside a VARCHAR column, but make sure the files are inside the server directory

Could you elaborate it because I am new to database

You can have a column of type VARCHAR where you can store the address of the images in the directory.These addresses can be retrieved during operation and the actual image can be retrieved from the server directory.

I understood what you have said but can u tell me can we give the location like E:/Image/
is it possible to give in database

Yes you can. But keep this idea as optional.
Check out any other possibility to store the canvas element where as image can be stored in DB.
