Black lines on photo

[Mel79hutch]

I'm hoping someone can help. I have sent some jpeg files to a friend after editing in PS. For some reason when she downloads them there are a couple that have these funny lines on the right hand side. It's only on some of them but they don't appear on my edited photos... can someone help?

This looks like fairly standard file corruption.  Just save them again from your master files, and send them to her again.  I'd be surprised if it happened twice.

Thanks so much Damien. Sorry for the basic question but I'm technically xhallenged.....I just open my edited jpeg file and save it with a new name? Or do I re edit my original raw file again?

Thanks

Your master file should be a PSD (or maybe a TIFF).  Have you read this article?

Thanks Damien....

I have read it now and am off to delete all my jpegs I was saving for a rainy day ?

Thanks!
