I have heard the first theory and decided to test it. I opened a high resolution photo in Photoshop and saved it with the maximum compression as a jpg. Then reopened it and saved again with maximum compression. After repeating this seven times I can see no further degradation after the first compression. The file size remains exactly the same also.
Yes. If a JPG is opened and saved, with no editing, by the same application, at the same compression ratio, you will likely see no visible degradation. But the thrust of this discussion has assumed that there is editing going on. If you make edits to the JPG and save it again, the parts which were edited will be recompressed and degraded in a way which may or may not be visible.
