when creating alt text for an image, what is the general rule of thumb?
Lets say for instance I have an image of a woman holding a hair dryer (i dont, this is just an example) and that image is used as a banner to advertise hair products (again, terrible analogy, but for the sake of learning alt text lets run with it)
Now, is it best to have the alt text say….
"woman holding hair dryer clickable banner to hair products"
"woman holding hair dryer"
"banner image for hair products"
Im getting confused on this subject and not sure what the best practice is for alt text. Any help would be very much appreciated
