Description
It will be useful if Trac shows previews for attachments in main ticket window.
This can be implemented using the Trac plugin architecture in order to allow extending the methods for generating previews for attachments. Taking into account overall performance of the system, the architecture should allow to run generating of previews in background when an attachment is added.
As a part of standard distribution, a displaying of scaled down images can be implemented:
- The size of scaled picture can be configured;
- There is an excellent Python Imaging Library that will do the work.
Similar approach can be used in other places of Trac, e.g. previewing attachments in wiki.

Undoing other stupid changes.
Why is anonymous allowed to change ticket properties anyways?

I've deleted those, thanks for the notice.

It's a trade-off. Besides TicketButchers, we also sometimes have TicketGnomes :-)

Thanks for refreshing the patches, nevertheless 2 hints if this should ever be considered for inclusion in Trac proper:
- patch should be against trunk, not the 0.11-stable branch which is in feature freeze
- patch should follow the TracDev/CodingStyle

Also, please move the "upload multiple files at once" functionality into a separate patch, so that both functionalities can be reviewed (and applied) separately.

Aside from the OverlayViewPlugin there are other plugins that may be of help, depending on your use case:
- ArchiveViewerPlugin: Browse contents in zipfile
- ImageTracPlugin: Include a displayed image with a ticket upon ticket creation
- IncludeAttachmentMacro: Display the text of an attachment
- TracCsvPlugin: Preview CSV files in wiki pages
Please note that none of these are necessarily compatible with Python3 or Jinja2 and will likely require some rework.
Probably, this feature should be enabled per-project or per-user because it generates more traffic from a Trac site
