... I'm just filling in for HPBEME while he's asleep.
Ha ha. Thanks Zybex
Any new skin should have a different name and be located in the Custom Resources folder or it will be overwritten when you update.
In my post above, I explained how I set up the file so it will not get overwritten - it is not necessary to put it in the custom resources folder so long as you take the steps that I have done. I have a dozen+ skins of my own (a bunch of variations on my 2 primary versions) as well as a number of MC default skins I've tweaked/renamed, and they never get overwritten.
I created it by deleting the 2 small stars files and renaming the large stars file list_rating-1,5x.
The different size image files is not how you're interpreting it. It is for automatically adapting to different monitor resolutions and window OS scaling settings. The fact that you are able to delete 2 of them and MC defaulted to the remaining rating image without any issues confirms that for this particular MC display element, it is not needed to create specialized monitor resolutions/scaling images. I don't do it with my skins, and the rating images display just fine regardless of monitor resolution/scaling.
None of that probably means anything to you, which is fine. That little bit above is really intended for other skin authors.
I created it by deleting the 2 small stars files and renaming the large stars file list_rating-1,5x.
Problem is then a white rectangle area appears around the stars against the alternating grey lines.
How do I have the large stars without the white rectangle around them against the alternating grey lines?
I hope the photos and explanation are easy to understand.
That rectangle around the stars should not be there, and is indicative that the transparent portion of the image is not 100% transparent. I don't see a rectangle around the stars on my monitor - probably because I have my brightness set fairly high so the background rectangle "washes out". I selected the whole transparent area and deleted it just to be sure no trace of color remains. The result is the attached file. Copy/paste it into the folder I provided you earlier, and see if that fixes it.
I also included a 2nd version of the large stars/no dots with compact spacing. To me, the stars are way too far apart and take up too much space. If you feel the same way, rename the 2nd file
list_rating-2x.png and paste/overwrite the existing file, otherwise MC will not recognize the image name and thus not use it.
Best of luck and please report back how things turn out.
