Open the photo and do a screen capture, or use Preview to grab a screen window, or selection. That should strip everything, but that is cheating, and the point was that fake location data could be put in the file.
I'm still puzzling over the other problem. These are 1.5 meg files. Huge. Then I think I'm fighting compression.
I tried to find the picture size, didn't work. Converted to hex from the file info (which also reads the basic exif but not the GPS coordinates), that didn't work. The rest of it is in some crazy code and symbols.
I know I can alter the date and time, mfr, device name, version (unless it gets munged or doesn't match the same # of characters), then it's too much for me.
Linie after line after line of gibberish to wade through. I'd really like to find those GPS coordinates, have to be in there somewhere as well as all the rest I want. There's probably a program to convert it, looked but didn't see anything that looked like it would work for me.
I deleted most of the data hoping to isolate the exif and get another readout, but I destroyed too much data to do anything with it.
If I copy and paste the date and time part into my post here, it comes out wrong. The only thing to do would be a screen capture and upload it which I'm not in a mood to do. Plus it's copyrighted by Hewlett Packard. I saw that much lol.
I love fooling around with stuff like this. Few years back I hid a message in a graphic. Only two people out of I don't know how many in that group figured that one out, and I made it pretty obvious where to start with it, just not how to read it. All I did was make a talk balloon with a white background, then changed to text and changed the white to one step down on the three hex color codes. Visually it was impossible to detect, but there were a couple different ways to process it to make it readable.
