Can we get uploaded image path in wordpress by filename? Actually I know the way in PHP that will parse all files in the uploads folder, and matches the each file. But that way will produce high load on server, whenever I will run this script.

Is there any other possible way?

Thanks.

Note: I do not have any posts linked with it. I just have image file name. By that only I need to find the full image uploaded path e.g. http://www.abc.com/wp-content/uploads/2013/02/test.png
