Does anyone know where my image goes if I delete it in the "open file" window (ctrl + O -box)? Does Photoshop have a trash can?
On Windows the File - Open dialog is provided by Explorer. Thus, if you've set things up to use the Windows Recycle Bin (the default), you should be able to open the Recycle Bin and Restore your file.
Nope, nothing there. The same thing in brdge as well, the images seem to vanish...
