Weird artifacts appearing in image after upload

[ArchRival]

These are images i uploaded to photobucket. The speckles appearing aroung the bright stars are not present in the original jpegs, only in the uploaded ones.

Does anyone know how to solve this problem? The speckles look like noise, and they make viewers think i'm incompetent in my post processing ;( ;(

It seems like photobucket use a higher compression level to store your JPEG photos. There is nothing you could do except looking for another image hosting server.

Some image hosts compress your photos.

Okay, found a solution. Trick is to reduce the quality of the image myself before uploading, so the hosting site wouldn't use their crummy algorithm to reduce it after that.

Those are JPEG artifacts. Present when your photos are compressed.
