store persistence data in browser ( chrome )

  google-chrome, javascript

I need to store large images in browsers persistence storage so that it will not get deleted when I close tab or browser.
I need to upload those images to the server and images are coming from X-Ray machine directly to browser using twain API.
since those images are not stored anywhere else I need to keep them in browser persistence storage until upload is completed.

Local storage will not work since it have limit around 5mb to 10mb and my images are around 15mb and I need to save multiple images at a time

is there a way to store those images in browser?
