I'm talking about all the extra stuff encoded in them, including the type/ model of camera that took the photo, copyright info, etc. Vista has a feature in which you can edit/ delete them by going to Properties -> Details tab but does that completely 'clean' the picture? If not, is there another way?
As Sensei said, it's a lot of work, but the safest way to do it is by copying the photo/image from the main file into a blank file. Basically, select all, copy, paste into a new document, and save. Tedious, but perhaps worthwhile. Mike
Ah I see so by removing the 'details' from the properties' photo doesn't do that. The EXIM data, is that what it's called? So either by copying the photo or with Adobe Bridge which I have got but never used? EDIT: Is it the meta data -> IPTC in Bridge? By the way, does anyone know if this is how companies like SplashNews or others that copyright their photos can track them down? By searching for the IPTC data? Thanks.
Usually watermarks on a photo are a dead give away, but if you remove anything like that on the photo, The other way they could find them is in Google, just lookin' for images that pop up in the Google images search. Following the web link and walah! I had once heard if you make three changes to an image it's not a violation of copy write but i don't believe that for a second. Best bet is to just drop em an email asking permission to reuse their image for non for profit purposes.
For sure ACDSee can do this automatically on a set of images. I am not sure for irphanview. You can use http://www.mindgems.com/products/Easy-Web-Gallery-Builder/Easy_Web_Gallery_Builder-About.htm to add watermarks. It will soon support removing EXIF info too.
it's actually called EXIF data, and no, there's no 'simple' way to search for it, they'd have to somehow get to your site, download the image just in case and then check the file individually. I suggest you clean them if you're paranoid and you only have a couple, but if you've got lots and they do want you to take them down, they will send you a message asking you to take them down and give you a chance to remove the offending material anyway so there won't be charges and fines or anything. Hey, if they didn't want people to see it, why'd they put it up online! EDIT: you could also give them credit for the image in the tooltip(alt text) or in the source code commented out, as well as in a caption on the page, that way you're citing where you got it from. Personally I'd do the tooltip one...
There is a special tool which can remove date stamps and other unwanted object from your photo. Photo Stamp Remover can be downloaded from www.softorbits.com site.
If your Digital Data means EXIF Metadata then you can go With Windows Explorer to remove it. open Windows Explorer select all the image files Right-click and select Properties Click over to the Details tab Click the Remove Properties and Personal Information link Now you will able to remove EXIF Metadata.
