Lately I have noticed that the scaled image you upload is very blury and poor quality.|
For examaple on this page: https://www.astrobin.com/383607/
If I compare with the original image you can really tell the difference:
Why has the image quality gone down?

Looks like it has been reduced in size to 620*411 then expanded in size to about double.|
I downloaded it and it look sfine by itself, just a bit too small.
What are the guidelines for the images so we can get them to look good on the page?

no, AstroBin does not reduce and then expand again.
Your original upload gets compressed with the following settings:
AstroBin prefers not to do any guesses, so it doesn't change anything besides bilinear scaling at maximum quality.

|Cool, thanks. I'll have another look at the processing and see if there is something I can do.|

After a bit more testing, I have found out what the problem is. Indeed AstroBin is not expanding out; Windows is.
In windows I have display scaling set to the default of 150% (for my 4K monitor).
In Pixinsight, I can see the image pixel for pixel with my monitor (i.e. it does not apply the scaling). Here it looks nice and sharp as expected.
However in all my browsers the 150% scaling is applied, so the image is then a little blury. If I turn off the windows display scaling then all looks sharp, but quite small.
I wonder if there is a way for the AstroBin site to tell the browser to NOT scale an image…

I'm no web developer , but after a bit of searching, perhaps this link could help.|
I'd like to request that the following changes be considered:
