Make some modifications, eg, cut, change contrast
Click Save
Close
Open again and observe that there are no changes.
Click edit and observe that changes have been applied.

Are you sure the preview is not updated, or is the preview still cached by your browser?

Are you sure the preview is not updated, or is the preview still cached by your browser?

Ehmm, how to get know that? And what to do?

UPD After forced refreshing of the page it updates! So, the right logic should be the following:

I edit an image
click Save button
it should refresh
it should recreate the preview and show it

Otherwise it is not obvious whether the changes have been applied at all.
