Dynamically add both watermark image and upload image in asp.net c#
As we previously learn about how to add watermarktext on upload image and how to add watermark image on upload image when logo(image) is fixed but now we learn about how we can add watermark image (logo)
and upload image according to our requirement means we can add watermark image according to our needs.
Suppose we have 3 logo (water mark image) and we
upload according to our needs then this code defiantly will help you.
