Wireshark · Ethereal-users: AW: [Ethereal-users] JPG-Export from captured file (TCP-Reassembly)

["ThEbIg" <the-big@xxxxxx>]

Ok, so i have to wait for a 0.10.8 version for SUSE Linux.

In my version 0.10.3 are not all options available. Only 2 options for HTTP
and the correct option for TCP.
But it works with small jpgs ~ till 2KB.

Thanks for help!

...and if any of that can't be done, e.g. because HTTP doesn't have
those preferences, or JPEGs aren't dissected, upgrade to a newer version
of Ethereal (I don't remember when those were added, but if it was after
0.10.3, the original poster will have to upgrade - items in the Wiki are
likely to refer to the current version, so anybody running older
versions might find that they don't apply).
