You
can open and import images in various file formats. The available
formats appear in the Open dialog box and the Import submenu.
Choose
File > Open.
Locate and select the file you want to open.
Click Open. In some cases, a dialog box appears, letting
you set format-specific options.
There may be instances when Photoshop Elements cannot
determine the correct format of a file. For example, transferring
a file between Mac OS® and Windows® can cause the format to be mislabeled. In
such cases, you must specify the correct format in which to open
the file.
