[Plugin: Image Rotator Widget] Does not validate

Hi. I can’t get the widget to validate. It states:

Line 94, Column 354: required attribute “alt” not specified
…k/wp-content/uploads/2012/04/31.jpg” />

• <img src=”https://tornadoeducat…
  ?
  The attribute given above is required for an element that you’ve used, but you have omitted it. For instance, in most HTML and XHTML document types the “type” attribute is required on the “script” element and the “alt” attribute is required for the “img” element.

BUT all of my images DO have alt tags.

Any advice would be awesome.

Cheers.
