Prestashop thumbnails of the menu are not displayed + 2 javascript updates

Hello there, We need three things. First one is about fixing the thumbnails category on our horizontal menu. This error is well known in Prestashop, many users have this issue, so it requires to check online for solutions. We tried one but it didn't work out. Second one is about changing the percentage of a diagram pie chart we have because it counts in terms of entries instead of in terms of values. Last one is about putting the same tooltips from a javascript diagram to another diagram. Should not be complicated. See more on the pdf attached.
