-------------------------------------------------------
I have tried it and the result is as you describe, Nick (i copy and paste the
result below). Then i guess the problem is in the way i try to detect it (java
code). Thank you very much for your answer, and sorry to have filed an issue
which was not a bug.

> Wrong mimetype detection
> ------------------------
>
> Key: TIKA-1538
> URL: https://issues.apache.org/jira/browse/TIKA-1538
> Project: Tika
> Issue Type: Bug
> Affects Versions: 1.7
> Reporter: Miguel
> Attachments: Product345037-000.jpg
>
>
> [SCENARIO]
> - Working on a "supposed to be a valid JPEG file" (the file is attached to
> this issue report), which is correctly detected and treated by a browser,
> etc. (Detection works well for almost all other checked images).
> - Using tika-app-1.7.jar
> - Java code snippet:
> Tika tikaObject = new Tika();
> ...
> // image is a byte[] containing the JPEG file
> String contentTypeTika = tikaObject.detect( image );
> [RESULT]
> detected mimetype is "application/gzip" ("application/x-gzip" if using
> tika-app-1.4.jar or tika-app-1.5.jar)
> [EXPECTED]
> "image/jpeg"
