Re: Coca-Cola 

Sorry if I rudely didn't drop an explanatory note at your talk page; it was rude of me and poor behavior.

Please see our Manual of Style to understand the correct formatting and appearance standards. The one issue with your additions is that the captions for the images are entirely too long and full of extraneous information; image captions are not museum display cards and do not serve to detail every single item appearing in the image; Wikipedia is an encyclopedia, not a museum. They should also never state "note the x" or other similar attention drawing text, per WP:W2W, one of our guidelines on writing prose. They also had inappropriate use of capitalization, boldface and other formatting issues. For example, ALLCAPS spelling is never used for emphasis, as it is read as shouting on the Internet. 

As for the Coca-Cola additions, I took them out for lack of relevance. The Coca-Cola article is about the drink, not the company; that's at The Coca-Cola Company. The information in those images is better placed there, but in the article text, not the image caption.

The other reversions were based on similar concerns; the same sort of formatting and caption length issues were present there. In the one article, for example, the caption was nearly as long as the rest of the text in the article, when that text should really go in the article's body text instead. 

Once again, my apologies for biting your head off, as you were editting in good faith. I hope that my poor behavior doesn't turn you off to the collabrative process and that, with a bit of polishing, you can add much to our growing base of knowledge. (As a ln aside, the correct way to sign a post is with four tildes (~).)
