Spelling error: "... compression has no affect on image quality ..." should be "effect"
In the GIMP documentation: Part II, Chapter 6, Section 2, "Preparing your Images for the Web", Subsection 2.1, there is a Pinned Note (at the foot of the page) associated with Step 3. The third sentence of that note starts:
Maximum compression has no affect on image quality ...
Affect
with an A is a verb. The corresponding noun is Effect
with an E
(in all variants of the English language). So the text should be changed to:
Maximum compression has no effect on image quality ...
