Sharing a nice tool for reading Metadata off pictures (does lots more too)!
EXIF Tool is FANTASTIC! Free too! Download here:

I use it to extract data off photos, but far below, I’ve listed from the EXIF Tool site, a small column of other uses for this tool.
Spoof Deconstruction Experts and Law Enforcement, EXIF Tool reads, and writes. There are other progs that are desinged specifically to allow the user to distort Metadata from Photos (and other digital devices). Keep this in mind both when your looking to show evidence could have been distorted by a spoof, thereby interjecting doubt of scientific data, and from LE perspective - try to white hat your scientifically sound evidence. This way your ready for any doubt that the other side might cast on the evidence.
Picasa and other free online progs can see photo Metadata too, of course, that is how they are showing you Lat/Long from GPS enabeled device photos that have apps enabeled for location log. EXIF Tool gives you full control over ALL the collectable MD, very professional. With this, you have the 'back end' of Picasa in you shop.
Other things that EXIF Tool can do (from their site):
•Powerful, fast, flexible and customizable
•Supports a large number of different file formats
•Reads EXIF, GPS, IPTC, XMP, JFIF, MakerNotes, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP, ID3 and more...
•Writes EXIF, GPS, IPTC, XMP, JFIF, MakerNotes, ICC Profile, Photoshop IRB, AFCP and more...
•Reads and writes maker notes of many digital cameras
•Decodes a riddle wrapped in a mystery inside an enigma
•Numerous output formatting options (including tab-delimited, HTML, XML and JSON)
•Multi-lingual output (cs, de, en, en_ca, en_gb, es, fr, it, ja, ko, nl, pl, ru, sv, tr, zh_cn or zh_tw)
•Geotags images from GPS track log files (with time drift correction!)
•Generates track logs from geotagged images
•Shifts date/time values to fix timestamps in images
•Renames files and organizes in directories (by date or by any other meta information)
•Extracts thumbnail images, preview images, and large JPEG images from RAW files
•Copies meta information between files (even different-format files)
•Reads/writes structured XMP information
•Deletes meta information individually, in groups, or altogether
•Sets the file modification date from EXIF information
•Supports alternate language tags in XMP, PNG, ID3, Font, QuickTime, ICC Profile, MIE and MXF information
•Processes entire directory trees
•Creates text output file for each image file
•Creates binary-format metadata-only (MIE) files for metadata backup
•Automatically backs up original image when writing
•Organizes output into groups
•Conditionally processes files based on value of any meta information
•Ability to add user-defined tags
•Support for MWG (Metadata Working Group) recommendations
•Recognizes thousands of different tags
•Tested with images from thousands of different camera models
•Advanced verbose and HTML-based hex dump outputs
