Remove automatic exif titles for uploads

    When uploading to the media manager, if the image has an exif title, the system automatically uses this.

    I would like to remove this functionality, preferably without altering the core.

    Reason: We rename our photos locally pre-upload. If there is no exif title, the system will use the file name, minus the dashes and extension. This is preferred.

    Many cameras, especially Sony ones, enter “SONY DSC” for every photo’s title. This is poor for search engines, poor for readers, and makes sorting default gallery shortcode by title useless.

    So, is there any way to stop this from happening during upload? Do not care about altering what shows publicly after the fact, would like it never to happen so that automatic filename->title method is used always, and we can print/sort using title again.

    Thanks!

    Edit – looks like it’s in wp-admin/includes/media.php

    Want to alter function media_handle_upload()

    And remove this block completely:

    // use image exif/iptc data for title and caption defaults if possible
	if ( $image_meta = @wp_read_image_metadata($file) ) {
		if ( trim( $image_meta['title'] ) && ! is_numeric( sanitize_title( $image_meta['title'] ) ) )
			$title = $image_meta['title'];
		if ( trim( $image_meta['caption'] ) )
			$content = $image_meta['caption'];
	}

    So, any suggestions on how to do that without altering that file directly?

    It would be better to re-save the photo using an app like Photoshop that will remove the embedded exif data before uploading.

    Thanks for the response. Unfortunately that isn’t an option. We deal with images in a constantly in-flux manner which is time sensitive. Requiring another step in the workflow before they get online wouldn’t be good. Not to mention working from mobile or tablets where that isn’t a quick or easy task.

    You may look for a plugin that can manage your EXIf data:

    Thanks I will take a look. I’d prefer to stay away from plugins as this is an integral part of the system for us. If the author ceases development, we’d be stuck.

    Is there no filter or action hook available to remove and then re-add this function, just altered? That’s the part I’m not seeing, if its possible.

    I checked out those plugins, and one of them lead me to a method for getting the end result.

    adding a function to add_attachment which declares the title and cleans it will effectively remove the exif processing.

    Putting this in your functions file should do trick

    add_action( 'add_attachment', 'your_function' );
function your_function() { function stuff }

    Though it would be much easier to turn that feature on/off, or access it with a hook to disable it. May go suggest that.
