So why wasnt it like that before and it is like that now? I optimized the images and its the same and I dont think the problem is the image but the transparent header. When reloading you can see the previous pink header not the image appearing.
Is that your solution? Its your theme and you should fix that to be honest. Your solution is “just dont use header transparent” well I want to use it but dont want to see the old header under it. Thats something easy to do for sure I have never seen that happen with other themes.
