Is there a way to stop ppl from editing jpegs??

I recently made a pose card to help me remember all the poses i like to use when shooting in the studio. some of the pics i used were my own, but other poses i used were from the net (just to make my own personal pose card). One of those jpegs could not open in photoshop, but could open in the windows viewer. So i was wondering if there is a way to 'corrupt' a jpeg in order to protect my own images? Or is there any way at all?
Thank you

I'll bet that if the jpg opened in the viewer it could have been opened in Irfanview or a similar application and then resaved as a jpg, tif, bmp, psd or any one of a dozen other formats that would open in PS. Also, its shocking to hear, but there are a few other editing apps in the world, other than PS. And even Flash images can be copied with a screen capture. So the answer is, not really.

Don't post any of your images online is a pretty good method to protect your images.

Yep, that pretty much sums it up, if it can be seen on the web it can be stolen. There are a few fancy bits of code that can disable the right-click to save option but screen captures are a very easy alternative.

You can always convert your JPEGs to PDF format and password protect them.

I guess watermarking is the best option then

As easy as it is to develop a watermark, that is how easy it is for some to remove the watermark.

I would not be too worried about someone stealing your images, it is envitable and will happen... unless you do not post them.

The only solution: post mucky photos that nobody would want.

That, too!

I had this one guy tell me he made a GREAT 8X10 print from one of my 800px, 100KB images posted here. I asked him to tell anyone who he showed it to that I didn't make it for him.
I usually crop the web images so they aren't in 2X3 format. Last week one guy emailed me & complained that he couldn't get a 4X6" print from it.
Sometimes I'll add a black or background colored border to throw it even more out of proportion.

my confusion is why would anybody purposely go onto this forum and steal pictures lol

and PhotosGuy, that is sad, but hillarious that that guy make an 8x10 print from a size that small. Guess we've busted the megapixel myth...

I disagree with this. As long as you place your watermark over a "busy" area of detail in the photo, it can be darned hard to remove.

Have I miss read your question,
you want to know how to stop anyone using YOUR images but on the other hand you say QUOTE
"but other poses i used were from the net" .your happy to take photos of the net but you dont want anyone to take yours.
Why would you want to protect your images then.

Saving the image out of the browser cache is even easier.

Evey image viewed on the internet is downloaded to the computer of the person viewing the image.

Post low res and the DPI. Makes the viewing experience faster.

I remove water marks all the time... usually in the form of time stamps
Busyness of detail becomes much less of a problem when you know how to edit in different color modes, unless the watermark is composed of RGB noise, but those look too damn ugly to be worth applying.
