MVPBlurry picture quality in forum posting and reply due to bad server-side resizing
Bad picture quality in forum posting and reply due to bad server-side resizing.
It resizes to lower resolution but actually the size is bigger than original.
For example, my post iRule to Force Source IP to Specific Backend Node | DevCentral
It loads server resized 855 bytes picture from url:
https://community.f5.com/t5/s/zihoc95639/images/bS0zMzg5OTUtYmV3OXgz?image-dimensions=750x750&revision=1
Meanwhile, the unresized picture (higher resolution) are actually only 850 bytes:

I suggest dont use server-side resizing.
Let resizing done by browser.

I just saw this. My fault.
I agree and have seen that the defaults for the images posted act somewhat counter-intuitively. I believe, but have not yet looked into it all the way, that the platform is trying to prepare a lower-file-size image into the primary display but how it makes it's decision is somewhat opaque.
and, yes, sometimes it results in a blurry end-result; it'll take some testing for me to understand how/why that outcome presents itself.
Some things I know, that may help?
1) clicking on the image on the published post (not obvious) should bring up an image dialog that shows the full image.2) clicking on the image in the edit window brings up some options that may address what you are hoping to resolve. (see attachment image for controls).
Let me know what you think, and again, my apologies for missing this for several months.

i think the cause is the webserver's down-resizer uses improper config despite resulting bigger file size than the original.
i suggest do the server transcoding on upload,
meanwhile viewing/download it seems better to be resized by browser
