Minimalist mode or automatic optimizations are unlikely to be the problem here. This is most likely a problem relating to your computer failing to download the pictures from wherever the module creator has stored them (EDIT: all images relating to modules have to be from imgur). This usually happens due to slow internet or unusual connection settings. I'm not quite sure of the resolution to the problem as I'm not sure where the pictures are hosted to test.

It seems others have been having this issue, maybe the host was not correctly responding.

Edit: Do make sure you have automatic optimizations and minimalist mode off though.

Edit: I believe this is related to the bug where imgur pictures have not been showing up correctly in the forums.
