You can add images as attachments to Wiki pages and tickets. This
feature exists since 0.7.

I did not know that. Sorry.

What is the syntax to use in the Wiki to reference an attached file at a
given place ?

Thanks.

I've just tried.
However, it does not work as (I) expected:

The image is attached as any other file to the Wiki page, and the page
cannot reference a self-contained image.

Ie, if I add "image.png" to WikiPage, and
WikiPage contains a reference to

http://host/trac/attachment/wiki/MediaOptiques/logo-dvdxrw.png

the image is not displayed in the Wiki-rendered page, the URL is kept
untouched (ie the URL is shown, not replaced with the actual image)

Did I miss something ?

Thanks,
Manu

The way i do it is:
- attach the file
- click on the attachment link
- Copy the url of the image location, is something ending ?format=raw
- Place this url in the wiki page and you are in business ;-)

Yes, it can be done. It would be nice though if there were an easy and
straightforward way to reference attached images by using some wiki
shorthand notation, like PageName/image1.png.

On a sidenote, I also miss the possibility to use relative paths to
images; things like images/xy.png or /images/xy.png are not recognised
as images, and there is no way (read: no syntax) to actually force an
image tag with whatever URL I want (think dynamically generated images,
with URL ending in .cgi/pl/py/whatever, or image formats not known to
Trac).

But I guess I should open a ticket instead of stating this here :)

Cheers,
Dan

That would be a nice feature.

There is a way to solve this in wiki pages:
{{{
#!html
<center>
<img
src="/trac/beowulf/attachment/wiki/SaraCFengineConfig/bas.png?format=raw">
</center>
}}}

Absolutely correct. In my eyes a workaround at best -- not the point of
a wiki (low threshhold publishing and all that), having to fall back to
arcane wiki processor magic and HTML, is it? I don't expect the average
user to go to such lengths when he just wants to display say some
.bmp's. Easy things should be easy. Some friendly wiki syntax like
IMG:/foo/bar.bmp or [img]/foo/baz.png[/img] or some such would be much
nicer, I guess.

Cheers,
Dan

Replying to myself now...

FYI: After double-checking for open tickets on this, I've created a new
ticket about enhancing the inline image handling:

http://projects.edgewall.com/trac/ticket/739

This should cover all that was discussed in this thread, but if I missed
something, feel free to add comments to the ticket.

Cheers,
Dan

I agree on everything. Thanks for the bug submission.
