I wonder how I can format the errors if for example the image is to large or is to big in bytes?

Hi Allan,
Unfortunately it is not possible to change the default error messages appearance.

When it comes to formatting errors, it's all about clarity and organization. You might start by grouping similar errors together and using bullet points or numbered lists for easier readability. Also, highlighting key points or using bold text can really draw attention to the most important aspects. If you’re considering Custom Sign Printing, think about how the design can also convey information clearly—it's a great way to ensure your message stands out!
