I want to upload an large image to a current discussion. What is the maximum width in pixels? (I've searched the "Uploading Images" tips and don't see any guidelines.)

re: Image size?
You can post larger images if you use a 3rd party host, for example...
But note that because this forum is not a 'responsive' design (using CSS code which automatically resizes the pages and images to display properly on smaller screen sizes) this results pushing the page width. So I agree with sheepshanks, images that are 900 pixels or less are best for this forum.

As far as I know, using css to resize images would require the large images to be sent to the client computer and do the resizing while loading the page. This is slow and means extra traffic. Php supports server side resizing which is much more flexible and faster. Tjat would be my choice to fix this.

re: Image size?
Hi Jansimon,
You are correct, using PHP means you resize the image, save the downsized image, and then serve the downsized image to the client browser. Using CSS means you upload the full size image and then scale it dynamically at the client browser without modifying the image. CSS is the overwhelming preferred method in the industry. This is because bandwidth (whether bandwidth is defined as disk space or connection speeds) is seen as being freely available in this day and age. I would say that CSS is used in 8 out of 10 times.
I see the best long term solution as CSS because it provides the most flexibility. Having the best quality image archived means at any time in the future, as technology improves, you are well positioned. Once you have downsized an image, it losses quality that can never be regained. So in as the future connection speeds increase and disk space is a non-issue, you do not need to rescan every image in the archive. Of course, the best argument for resizing or otherwise limiting image file sizes is because the server storage is not what it should be. Hosting large numbers of high quality images uses more disk space but this is not an issue with any typical commercial web hosting company. The days of charging people more for disk space is over, the majority of hosting companies offer unlimited, unmetered disk space with their hosting plans. Terabyte hard drives are incredibly cheap and in fact the cost of a gigabyte in 1981 was $500,000 per gigabyte, today it is less than $0.03 per gigabyte.
But the existing situation here is to be considerate and not post high resolution images that basically break the page like the image above. No one wants to have the page stretched like this and have to scroll to see stuff. So I try to keep the images I post here to less than 900 pixels wide.

"Don, your image is too large. People prefer not to have to scroll sideways to read/view posts."
Understood, I posted it as an example of what not to do. This is also why I posted this comment

Frankly any image over 300 pixels wide is enough to cause a user to endlessly scroll if they are using many mobile devices.
