Context: LaTeX is a typesetting system. When compiling a document, a lot of really in-depth debugging information is printed, which can be borderline incomprehensible to anyone but LaTeX experts. It can also be a visual hindrance when looking for important information like errors.
For the image one there is an option to control if the image is immediate, or when if finds space to insert. Trouble is I have to look these up all the time...so what starts as an attempt at creating a cleanly formatted document often takes more time than messing around with a shitty editor like Word
If you don't want an image to float, don't put it in a float environment.
Exactly my point.
