Thanks:
I found this in
"Image name is not stored in the database.
In the original setup when you upload an image it is saved with a filename that includes the id of the K2 item/article that it belongs to. Therefore no data is stored in database, when image is needed on the website, the code just looks for the image with the filename that contains the item/article id.
The actual filenames of images look a bit odd because they are hashed, or encoded, by K2 when you upload them. For example image37.jpg can become something like 23438aesd2348swrtujh2341184.jpg. But K2 can still read the actual id (37 in this example) from that hashed/coded filename."
A file is named Image105 (with md5 hashing) and is stored in the proper directory.
When k2 tries to load an item image it tells it to just go out and get md5(item105) and see it.
There are multiple copies of the k2 item images in all different sizes so you can change the size that displays, and also, the source files are also stored.

And also, K2 storage the images in this location: /httpdocs/media/k2/items/src
