There's a whole bunch of stuff in a JPEG file which the app may be looking for.Originally posted by Platypus View Post
Here's the output from exiftool

Well it's a valid jpeg file, if that's what you wanted to know.
Why don't you try opening it on your Win7 machine, doing a "Save As" to overwrite it with itself, same filename, and see if it then works?
Anything that "listens" in a directory is likely waiting for filenames to arrive and is unlikely to be sensitive to what's in it. For example, take a text file, rename it to .JPG and see if that works.
I did notice that the filename is not 8+3 so could that be something to do with it?Leave a comment:

The app was purchased, I've tried Jpeg, JPEG and Jpg with no result. (I've also sent the developer the file but he hasn't got back to me yet, so I thought I'd ask the assembled brains of cuk)Originally posted by mudskipper View PostChecking the obvious
How's the app configured? Are file extensions case sensitive?Leave a comment:

Jpeg not a jpeg?
I've got an app which "listens" to a directory on my pc and when a jpeg arrives it fires up a sub app.
Now this works with a jpeg from a windows 7 machine, but not with one created on an xp laptop, anyone have any clues?
Here is one which doesn't get detected

(I've zipped it otherwise it would just open in a browser)
Thanks
