Hi,

I am making a script to generate counter image on the fly for the office

web site, and i have noticed that my dynamically generated jpeg images
bears following comment: "CREATOR: gd-jpeg v2.0 (using IJG JPEG v62),
quality = 100"

Does anyone know how to insert user defined comments into generated
images?

I looked around the net, and php API list, and found that i can only
read the JPEG header markers with exif_read_data. Is there a
exif_write_data function?

Thank you,
Alex
