Wireshark-users: [Wireshark-users] Exporting objects with invalid default filenames

Good morning.
 
I am using Wireshark to capture a large number of JPEG2000 images from a web site. The captured images appear in the "export/objects/http" dialog with mime type "application/octet-stream". But their default filenames are invalid, having been created from the original HTTP GET request. So "save all" will not save these objects.
 
I can select them individually and save them, but then I have to wait while Wireshark reads through all the packets. This is tedious. Is there a way to automate this? I would like to instruct Wireshark to assign incremental filenames to the objects, but I see no way to accomplish this.
 
Perhaps this could be done with Tshark?
 
Thanks
