Thanks for replay.
About EXIF, i cannot use it. As i wrote below, it's not installed on my hosting. And they will not at this point.
I want to build a gallery.
I want to use information such as title, description, creation date of image (file properties) to bring information to the page.
I dont want to use sql at this point.
I now found about IPTC that i might use.
Reading and checking now.
May be there is more easier solution?
As i wrote, i need to deliver image information to the page. such as title, description and date (for example) without using database or long filenames.
Thank a lot.
