Can't upload logo

Hello, I have another question. Various people have asked about having the site title next to the logo, which is not an option, and you’ve suggested creating a logo with the title as part of it. I’ve done this but I can’t upload it. Or rather, I can upload it to the library but the theme won’t accept it. I can, however, use a much smaller logo without the site title. Is there a size limit for the logo, and if so, is there any way round it?


Never mind, I figured it out. 5 minutes late as usual!
