I have a JPEG GET request in my PCAP as below but when I export it, it's not a valid JPEG file

Any ideas?

Change the format to Hex Dump and look for a matching file signature

The screenshot is hard to read. But my gut feeling is that this i actually not a JPEG image based on the first characters in the response.

I had the same idea... if you look at the hex data, does the image start with FF D8 FF? See: https://www.filesignatures.net/index....
