I am at day 1 of trial and uploaded a photo but now i see only a 1mm thick line from this photo and not the entire photo. how can I perform my trial ?????

A screenshot showing the issue would be worth a thousand words here. Can you post an image showing the issue?

At first reading, it could be a corrupt file. It is also possible you inadvertently cropped it to a line. Without more information it is impossible to tell what is going on.

You are very good. That was the bloody crop button which I might have hit by mistake;-)
