if the prefix is full of 0's it doesn't matter. E.g 000001 0000000001 001
If you have any more questions let me know

1,448 Pointsi did this::: In the image tag, change my picture, joy.jpg, to sam.jpg. You will also need to change the alt attribute to say Sam, instead of Joy.
but its telling me to do this::: Bummer! The 'alt' attribute of the <img> element needs to be set to "Sam"! Set it like this: <img src="sam.jpg" alt="Sam">

28,694 Pointsit should work. I just used <img src="sam.jpg" alt="Sam"> and it worked (I copied the text here directly from my challenge before it passed). May want to retry challenge in the event it's a random glitch. If retrying doesn't work and your code is solid, then you may need to email treehouse.
