Hi,

I seem to have a problem with extracting EXIF data from images that I am posting at my (new) photoblog (see URL below). I've read various other threads on this forum and have tested the exifer1_5 program using the suggestions offered by others (using index.php in the exifer1_5 directory), and this shows the EXIF data to be missing from the images. I have a development build of the site running on my local machine, and I can post images using this and the EXIF data is retained. When I post to my live site, EXIF data seems to mysteriously disappear...maybe in the upload process...?

Has anyone else come across this or similar problems before? I'm running 1.4.3 on a Linux host with PHP 4.4.1.

Thanks for any help!

Your images dont have EXIF data!!

At upload process there isnt any modyfication of images. Check if you really uploading photos with EXIF data inside of them!!

Yeah, one of my first thoughts was that something must have happened to the images before I uploaded them. But on my local dev install of pixelpost I can upload an image that clearly has EXIF data present and when I check the created image in the pixelpost/images/ directory, the EXIF data is missing.

I hear what you're saying about the upload process itself not altering the image, but something screwy must be happening somewhere for this difference in the two images.

I wondered if anyone could think of any possible MIME type settings that might be needed in the webserver config...? I'm clutching at straws a bit here :)

Thanks for any further suggestions.

I finally figured out the problem. At some point (sadly, I don't remember doing this at all! :confused:) I must have installed utok's resize hack into the admin index.php. I did this before the thread went on to discuss missing EXIF problems!

I've rolled back to the original 1.4.3 release admin index.php and EXIF data is available again...YAY! :)

slightly off topic, but there are great tools available to copy exif data from 1 file to another - search for jhead -- now, if this was included with the resize addon, exif would not be lost!
