Re: Posting Images - ...especially *large* ones
*Can't help noticing that very recently more and more people are taking to posting images within their posts (particularly in the Unmanned Probes folders) -- and some of them are rather large, with noticeable "bulge" of the post itself as compared to surrounding posts. Does this have the potential to weigh down a thread and more easily cause it to collapse? IIRC, Josh (?) has mentioned previously that long (wordy) posts seem to cause a thread to collapse more easily.
I myself have -occasionally- posted images, but usually post hyperlinks.
Just wondering, especially as there is a noticeable download drag when opening up a page with huge images in them.
Thanks!

Re: Posting Images - ...especially *large* ones
It is too bad there is no way to set the size of the image when you post it. It would also be nice if there was an alternate text attribute so if the image link got killed a post that had formula images would still make sense.

Re: Posting Images - ...especially *large* ones
Hmm, I doubt they'd allow the threads to collapse, and I just realized something, that you can make a post with 65kB of text, that's huge, that's like a friggin novel. It is true that there seems to be a correlation between long posts and threads collapsing. I'm contemplating turning that 65kB post length limit down a bit, but I don't know what it would do to the posts that we already have in the database. (We seriously need to switch to MySQL Adrian, heh.)
Anyway, being with dialup has its problems, I hate picture loading threads (though I tolerate them because they prove interesting). There doesn't seem to be a way to limit the size/resolution of the images, though. The only way I can think is for mods to go in and edit the images down, but that honestly is a bit excessive.
An alternative is to post sized down images on ImageShack (which I do for some people whose icons are huge), but then that comes with its own copyright problems and I don't even want to think about it.
But nah, to answer the question, it shouldn't affect the database or anything, the images are hosted offsite. The load times are due to the images being big probably. Try loading a picture intensive page on dialup! 
Hope that answers your question.

Re: Posting Images - ...especially *large* ones
Is the code button for html?
Example html code line:
<P ALIGN="CENTER"><A HREF="Project Constellation Editorials Archives_files/ss1-cartoon.jpg"><IMG SRC="Project Constellation Editorials Archives_files/ss1-cartoon.jpg" BORDER=0 WIDTH=428 HEIGHT=321></A></P>
The original time this was posted on Jame's Project Constellation site it had a width=*** that were off the page, changing to something smaller worked fine in that case.

Re: Posting Images - ...especially *large* ones
Anything more than 320 x 240 should be automatically resized.
A link to full size could be provided below.
I am only running 600 x 800.

Re: Posting Images - ...especially *large* ones
HTML is disallowed because it would let people do naughty things, and we can't have that. Resizing how images are displayed could be helpful, but it wouldn't stop the slow page loading Cindy notices. Heh, for example SpaceNut had a .jpg for his Avatar that was several hundred k, but IkonBoard only lets you have 64x64 icons. I resized his, saved it as .gif and uploaded it to ImageShack.

With the right compression you can manage fairly quick loading images that are fairly small a 640 x 480 image I posted to http://www.newmars.com/forums/viewtopic.php?t=209]this thread was only 44kb in size and it did not drop too much in getting the file size down so far.
However I have to agree that image heavy threads can be a pain to load on dial up, thats one of the reasons I stopped posting as much to New Mars. My dial up was so slow the early Spirit & Opp thread pages could take an age to load, thankfully the dial up has gone and I can view the pages quickly on ADSL.
If it becomes a problem with images dragging down the threads, I'm quite happy using a low res small image with my posts and placing a link to a higher res one.
