B--- after refresh this page by browser, the photo is shown in a flat page without layer.
Now, questions about above:
Q1---- In A, the page title is not related with the photo. How to let photo display in B directly without refresh the page?
Q2--- If Q1 can be solved. There is still a question. in B, when view next photo, the title of page remain photo's ID or other information of FIRST photo, not change to the information for next photo.
Can they be improved?
