Meaning of "Bloody Beautiful" [closed]

Bloody in this context is an adverb to add degree to the adjective beautiful. It's not common in American English but is very common in British English. It's considered a mild swear word, and thus adds more emphasis than a more benign word like very.

The author is promising to help your photos transform from "good" to "beautiful" -- but not just beautiful: extremely beautiful.

For example, see: http://dictionary.cambridge.org/dictionary/english/bloody

It means "really beautiful". "Bloody" simply serves as an intensifier.

Bloody: Used as an intensive (Chiefly British Slang)

(American Heritage® Dictionary of the English Language)

On a separate note, I suspect the reason the author put "bloody" next to "beautiful" is because of alliteration:

alliteration: the use of several words together that begin with the same sound or letter in order to make a special effect
