Microsoft Photo Info allows photographers to add, change and delete common “metadata” properties for digital photographs from inside Windows Explorer.
When installed, a new “Photo Info” item appears on the context menu for files selected in Windows Explorer. To use, simply select one or more image fiiles, right-click and choose “Photo Info” to open the Photo Info properties editor. You can edit metadata for files individually, or all together as a batch. Photo Info reads and writes metadata in IPTC and XMP formats (depending on file type). It also provides enhanced “hover tips” and additional sort properties for digital photographs in Windows Explorer.
Microsoft Photo Info runs on 32-bit versions of Windows XP (with Service Pack 2 or later) and the Windows Vista operating systems.
