i usualy do that but there was a weird problem that it didnt update it i tried to "refresh" and stuff like that but still didnt see a change
Could've sworn I already voted on this one o:! Did you remove it and resubmit? If you want to make edits, please edit the original instead of submitting it anew. It'll get through the public queue faster that way, since resubmitting resets all the "yes" votes you've accumulated.
That's actually most likely on your side, the image updated, but your browser was showing you a cached version. If you clear your cache or hard-refresh (ctrl+F5), the new image would show up.
The reason it happens in the first place is a PJ problem though - PJ doesn't mark the file as changed, so your browser doesn't know that it needs to redownload it.
