Hi all,

This is probably a vary basic question but here it goes..

How can I change a file (JPG FILES) properties like:

Title, Subject, Keywords, Comments.

Thanks in advance.

AFAIK title, subject, keywords, comments aren't stored in a jpeg file format ... not even in EXIF. Maybe if you explain where the title, subject, keywords, comments are coming from? What script, program or OS?

I get that information by pressing right button over the image (jpg) then select PROPRERTIES, then the Tab SUMMARY

I think that's part of Windows 2000 and XP. The info part the Indexing Service properities. The info is stored similar to EXIF. That's about all I can tell you.

comment blocks and the like are data chunks defined by EXIF, you'll need to get the file format spec for EXIF data to extract and change them..

This might help. First is EXIF format spec and the second is MS tag numbers (I think).
