Develop an app which converts normal image urls to twitter cards


#1

I want to develop a website which takes the url from an image which don’t have twitter card meta tags embedded in it and want to convert the image url to to a url which contains twitter cards.

Here is how I am going to do it.

Source image remains same. But I will redirect the url from my website which have twitter cards approved.
in the image source tag i will give source url and the remaining twitter cards will be pointing to my website which actually hosts the url only not the image.
in this way we can get rid of image upload time.
Tell me if this possible and correct.
