Other mistake: In the famous mugshot of Walter against a height chart, the chart goes up in nice 2 inch increments until 5'8." It then jumps to 6'0", completely skipping 5'10". Did they forget there are 12 inches in a foot, not 10?
Suggested correction: This picture was never used in the show. This looks to be fan-made. Regardless, this picture was never seen in any episode of Breaking Bad, so it is not a valid mistake.
If the picture was used as a promo shot by the production team then it could be considered a mistake. If it's fan-made then the correction seems to be valid. Does anyone know the source of the image?
I can't find a source, but I don't recall ever seeing it in the show or in any ads, and in all honesty, it's pretty low-quality, so I seriously doubt it's a real production or promotional image. (The masking around his ears is quite bad, the "bruises" are digitally painted on - and poorly so at that, etc.) I would be willing to bet money on it being fan-made.
It's not in the episodes as the corrector says. But I never watched the show when it was 1st airing, so I'm unsure if it was used as a promotional shot and as such can't say if the correction is valid (though, as you say, the quality is low) so I would lean to the correction being valid.
Audio problem: Throughout the series the engine sound from Walt's Pontiac Aztek sounds like a 4-cylinder engine, but the Aztek was only ever available with a V6.
Other mistake: The configuration of the front side of the house does not match the configuration from the inside. The outside view looking at the house from the street indicates (1) there are no rooms to the right of the garage (when inside there are rooms on the side of the garage). Also when looking at house from street side, to the left of the front door the house comes forward. When inside, (at least in episode 13, season 3) the inside of the house does not extend forward towards the street.
Suggested correction: If you research "The Breaking Bad House" you will see that the house used was filmed both inside and out, so this error couldn't have happened.
The garage is shown to have an interior door. Walt comes through it when he is showing baby Holly the money hidden behind the insulation. However, the is no corresponding door inside the house. The interior house scenes, at least most of them, must be a set.
