The maximum file size has been reduced from 2.5Megs to 512K

People posting PNGs either have to figure out how to compress them to something close to what they can do with JPG, or change to posting smaller images or JPGs.

The problem is - even the thumbnails the system creates from PNGs are huge - 1.5 Megs I saw yesterday for some of them - and this is one of the major reasons why loading some of the forum pages is so slow.

The forum is NOT a good place to put large numbers of huge images (or any other file for that matter) as we have no control over converting/keeping them, unlike the options in the Media Gallery - where we have the option of saving the original or not, converting it to JPG and setting max sizes that can allow us to better control basic transfer.

With many postings on a page each having several huge images, the system almost fell over on Sunday about 2:30PM - tied up trying to deliver to a couple of people with slow connections. I happened to be monitoring it and managed to restart the web server - but the load had grown from its typical 2-3 to over 100 (processes waiting) and every outbound apache process was in "wait" mode (as in waiting to finish delivering the contents of a page)

The problem with the system is not the original files so much as what the system can and does do to create the thumbnails which are what actually loads each page load. The originals only load if you click on the thumbnail - and so only one at a time per user is typically being loaded.

The system creates thumbnails but only of the same type as the original - PNG -> PNG or JPG -> JPG etc. and the major problem is the PNGs since they simply don't compress as much as the JPGs do.

The system only stores the original file name (with the PNG or JPG extension) so when it gets the thumbnail, the file name has to match (it looks in a different directory, that's all)

So, to eliminate huge PNG files in the thumbnail area I restricted the inbound files to max 512K

The option is to disallow PNG files totally and allow larger originals again since the JPG thumbnails are smaller by far and won't cause the problem that the PNG thumbnails of huge files does.

The only other alternative is to cut back (again - was 25, now is 15) the number of postings per page we show - but that still will cause problems as even 5 postings each with 5 huge files will be 5X5X1.5Megs (per thumbnail) = 32.5+ Megs just to view the images on the page - not counting smilies, and other images, etc.

IMHO big image files should be put in the media gallery. There is NO place in the forum for large image files. Screen captures of the stream should never be any larger than about 50K in size, otherwise it simply shows that people are doing it wrong. There isn't more than 50K of information in a single frame from the streams. If they have the stream at full screen, they're simply duplicating huge amounts of identical pixels - not getting any better "resolution"

I got caught up in something else yesterday and have not posted in the tech forum to explain this - anyone want to grab some of what is in this post and do it? I may not get to it until later today.

Thanks for the explanation, Richard.

A question - the first picture of the three above is 150 KB - so why doesn't it appear? I think my middle one is under 512 - though the third is bigger.

Is the limit 512K per picture or per post?

The limit (as far as I know) is per picture

somehow there were some PNGs that were as large as 6Mb in the area - don't know how they got there unless there is some other problem with the system's figuring out image sizes.

I can't figure out why your thumbnails didn't get created and show up here. No PNG thumbnails have been created since about 10:30AM yesterday.

Strange - will look into it farther.

I think both Delta OWL cams are down - usually more a problem on very windy days, but perhaps it's windier than it seems.

Will try to restart them in a few minutes unless Pat gets there first!

update - both now streaming.
