[Question] Weird Jpg issue

I have a .jpg that was cropped.
when I look at the thumbnail in Explorer(the preview of the picture before you click on it to open it up) still shows the full Image.

Now

I didnt know who else to post about very technical .jpg issuesd but the very people who use photoshop.

So my question is, Is there a way to "un-crop" the image because obviously windows is seeing the whole picture somewhere in the photo, so i want to get that back.

no i don't have the origional, the picture was emailed to me.
 
That is weird. It should preview at it is once cropped and saved as a jpg,

Are you sure its a .jpg and not a .jpg.psd? Better still - when opened , does it show the entire content as in explorer preview?
 
This doesn't occur too often, but isn't a big surprise, either.

There are pro level programs such as "Photo Mechanic" (by Camera Bits) that, to be safe, never will actually crop any pixels from an image. Instead, they insert a special tag in the embedded metadata that tells their program how to display the file if it is opened in that program again. Adobe Lightroom is another program that can be configured to act similarly (ie, cropping and other info can be stored in a sidecar file).

If another program attempts to view the file, it will likely not understand the company-specific cropping instructions, and hence, will simply display the entire image.

Why don't you post the file here and we'll be happy to take a look at it. I have both of the above programs, as well as some others that work the same way.

PS - A bit of history would also help -- where did you get this file, and specifically, what program was used to edit it, etc., etc...
 
The file was emailed to me. and I know the full picture contains nudity. So is it okay to post?
if not ill remove it

Its for Educational purposes I promise lol. I just have never seen this happen before and would like to know the cause and solution
 
no this is the "cropped" version. its all i can see, although the full version is viewable in the thumbnail only. so I am trying to "extract" the full version I will attach a screen cap to explain what i see.

wait yes this is the Full picture. But as you can see, there is more to it that windows sees ijn the thumbnail, but when i open it in any program, it is cropped like you see above
 
Ahh.. then Tom's hypothesis may be at work here. I don't have the application he mentioned and neither have Lightroom installed.

If you can get your hands on "Photo Mechanic", maybe you can undo it to get the full image?

Unless someone here has some idea what can be done........

Exactly. this is what I'm trying to do, I can get my hands on Lightroom and photo mechanic *cough* but idk if they will have that ability to reverse the image, and if so, how.
 
I'm not familiar with how Explorer deals with thumbnails but they are usually separate low quality images used to preview the image.
My guess is that even the the image was changed, the (low quality) thumbnail wasn't.

The original image is probably gone.
If you refresh the thumbnails you'll probably get the new cropped image as you're new thumbnail
 
It's not that, Steve... it may have something to do with how the image was processed and saved by the application it was done in as Tom pointed out. Maybe those applications can undo it?

I already thought of this and this was really weird

I tried to resolve the issue by changing the extension to a .png and the thumbnail changed to the "cropped" view as i would see if i opened it
BUT
When I changed it BACK to .jpg, I git the full picture as the thumbnail again.

Weird, eh?
 
The image I see is cropped just below the shoulders, ie, 300 x 169 pixels. I see the same thing whether I view it in the forum, or if I download it and view it using any of 8 or 9 image viewers that I have on my system.

However, when I look at it with dedicated metadata viewing programs such as EXIF Tool, Opanda IExif Viewer, and PhotoME, I see numerous strange things going on. For one, I can see a very low rez version of the remainder of the image (see attached). It appears that it was formerly cropped to 640x480 pixels, but I can only successfully find a 160 x 120 px thumbnail that was stored.

Also, much of the camera information is corrupted -- all I see is gibberish (aka, "Martian poetry") in most of these fields.

After seeing all that gibberish, I didn't bother trying to do a full quasi-forensic analysis to see if I could recover the entire image at its former 640x480 resolution. I probably could recover the rest of the image (if it was really important), but didn't because I suspect the "cropping" was accidental, not done by a program like Photo Mechanic that I mentioned in my previous post. It could have been corrupted in downloading from the little Olympus 710 point and shoot that she apparently used to her computer, or anywhere else along the chain of transmission to you.

HTH,

PS - I didn't see all the interest in my Photo Mechanic and LR theory that developed when I was busy looking at the data using the EXIF viewing programs. So, even though I now strongly suspect that the corruption was accidental, I opened the image in both Photo Mechanic and Lightroom (latest versions of both), and don't see any evidence that the cropping was intentional.

looking at the image name I'm assuming the cropping was intentional. I just don't know why Windows explorer was seeing something more than what I could see. Which was my whole question. But I appreciate all the effort everyone took into the whole issue. I'm sure Tom was rewarded with a present by being able to see the whole image. Lol. I just wanted the logistics behind it.
