Hello AlexandreGrothendieck, welcome to Wikipedia and thanks for contributing this nice photo of the Mittag-Leffler Institute!

Please note: According to the Wikipedia policy on user names "Usernames that match the name of a well-known living or recently deceased person" are considered inappropriate, "unless you verifiably are that person, in which case please note this on your user page". So, unless your real name is indeed Alexandre Grothendieck, please consider registering an account under a different name or changing your username.

Sorry. I have changed my username.DrTJJ 01:11, 23 July 2007 (UTC)Reply
No problem. By the way, your real name (or at least the name of a mathematician T.J. who has been at the Mittag-Leffler Institute this year) is contained in the EXIF information of the image you uploaded. (Forgive me for having been nosy, but as a great coincidence I had just read this newspaper article yesterday and was about to expand the EXIF article with regard to privacy concerns using this reference, which might be useful for you too if you want to avoid revealing such information when uploading pictures.)
Of course it is entirely acceptable (and to some users, like me, quite important) not to reveal one's real name here.

Thanks for the tip. I thought I had checked all the metadata, but I see now that more information about the photo was included in the exif data. I am hoping that the new "clean" version I replaced it with will be the only one that can be seen in the future. DrTJJ 03:53, 24 July 2007 (UTC)Reply
I'm afraid the old version is still available via the file history. Technically, administrators can delete file versions selectively. Bureaucratically, I don't know how to request this; the easiest thing might be to request a total speedy deletion by adding something like
{{db|Privacy concerns, see [[User talk:DrTJJ]], new version will be uploaded after deletion}}
to the image description page, wait for an admin to delete everything and then upload the clean version again.
