Skip some html elements to add alt tag in SharePoint master Page

I have deployed wsp .
When I have verified html using WAVE chrome extension.
One Image tag has no alt attribute.
Otherwise it works for remaining image tag in SharePoint master page.
Please help me with this.
I'm facing this issue on production environment.


Start by reproducing the reported missing-alt case in the SharePoint master page after deploying the WSP, then inspect how the control adapter handles image elements. Use the WAVE Chrome extension to identify the affected image and confirm that the adapter handles it without regressing the remaining images.
