error code in 'view page source'

hi all not sure if this is correct part of forum.....

my website is www.kevinmoran.co.uk

but upon inspection of 'view page source' for my home page, there is following error code below both my desktop and mobile logos -  logos that i uploaded myself, note desktop is png and mobile is a jpeg. I've tried many variations of each and diff pixel diemsnions as well down to 400px wide but i still see the following:

<!-- ERROR(@sqs/image): prop "width" is required --> <!-- ERROR(@sqs/image): prop "width" requires a positive integer, but received a non-integer value --> <!-- ERROR(@sqs/image): prop "height" is required --> <!-- ERROR(@sqs/image): prop "height" requires a positive integer, but received a non-integer value -->

How do i resize etc to get rid of this error?

Must say both mobile and desktop look ok to me - but i dont like error messages!

Thanks in advance

Kevin
