Thumbnail display in "full view" is implemented already. Let's take this entry: I insert a picture and scale it down via the "smaller" button:

Now if you display this forum in full view, the image is still shown as a thumbnail, which you are able to click in order to get the full resolution display. I don't know what is different in your case, maybe you are using an oder version of ELOG?

 Sorry for the delayed reply.

Ideally I'd like a config setting so that by default all graphics are presented at a fixed thumbnail size, so the users don't have to edit the image size every time they add one. Clicking on the thumbnail would open the image full size.

This would by default streamline loading and scanning through pages with many large images, whether in Full view of an entire logbook, or when viewing individual entries.

Have you tried Thumbnail size = xxx in your config file?

As an example, I created this same entry in the demo logbook using Safari.  As you can see there, the message is wrapped at the width that I set the text entry box.

No, '.txt' would definitely not be enough for me. I'm using elog to log all
administration of our network. In many cases, I simply attach a configuration
file. All those files are plain ASCII and none of them end in '.txt' - and I
would most definitely like them to be displayed inline like they are now. In
fact, this change was the main reason for me to upgrade to 2.5.4

Maybe a configuration option or a "display attachment" button would be the
best solution, then?

So to make everybody happy, it would probably be enough not to display inline any
*.ps file, is that right? Is there any other ASCII format, which should not be
displayed? PDF is binary, so it won't be displayed. What about long C files? Most
people want to see them. In the recent version there is the "Hide attachment"
link which can be clicked to not display an attachment inline. Mabe there should
be a "Hide default = 0|1" config option...

I think there should be size limit.  Imagine a multi MB text file (whatever it is;
elogd.c is already more than 1/2 MB and is likely to increase due to your
excellent support).  A client on an ISDN line would have to wait
several minutes and during this time elogd is busy and no other client can connect
(correct?).  Of course, if somebody really wants to see this file then there is
nothing to be done, but likely someone is flipping throught the messages using
to arrows on top to find the right entry....
So a configurable size limit seems appropriate, from which on 
only 'Display attachment' is displayed.  And/Or, for files
exceeding this limit, the first N (new config option) lines could be displayed.

But this should only influence ASCII files.  E.g. the behaviour for jpeg files
should not change, which is controlled by 'Hide default'.  Maybe a 'Display/Hide
defaut extension' option, where the extensions are listed that are to be displayed
is another idea, in addition to a 'Max Display ASCII inline size' option,
which can be set to zero to disable it altogether.

In any case, whatever you think is best.

Ok, I changed elogd such that only the first 1000 lines of inline attachments are
displayed, with a note of how many lines are truncated. By clicking on the attachment
name, one can still download the complete attachment. I guess the number of lines do
not have to be configurable, but if someone is not happy with the 1000 lines that could
be added.
