I'm torn between methods for using an image as my website header while still maintaining accessibility and making the site SEO friendly. I initially just used the image as a background image. I also saw how another site used the image as the background image with an actual text h1 tag but used CSS to place the text of screen so all the user sees is the image. Then there is using the image within the h1 tag and using the alt attribute for accessibility and SEO purposes. Any recommendations?
