It happened again Michal.

1- add main picture.
I get the window “loading your picture” with the progress bar
once the window closed I was waiting for the picture icon to appear, I decided to add the second picture.
I chose the second picture. this time the “loading your picture” did not show up.
so I think something is wrong and try to add again but nothing happens after choosing the picture.

I refresh the browser. I loose all my work but I can add again.

I did the same thing again. but this time I waited for few minutes, both pictures appear.
So it seems like if you try to add another picture back to back without waiting you loose the “loading your picture box”

2- again toward the end of my project as I added the last 3 pictures, no link appear.
so I choose 3 pictures and click on open. the “loading…” box appear.
I open a new browser to read some news. I come back to it almost at the end. I waited there, The "loading…’ box closes but no link even after 5 minutes.

the pictures are about 5MB each
windows 8.1
IE 11
intel I7 processor
8GB RAM

Chose 3 to 5 pictures about 5MB-6MB when trying to reproduce.

Next time I will record screens
