I was sent a PDF that was an InDesign one pager with 1 layer and a master page. The master page contaims two images, no alternative in the images. When it was converted from InDesign to PDF, tags enabled, and I fixed some the issues; I keep getting the Checker saying that the one of the two images does not contain alternative. I can plainly see the alternative text using TURO and looking at images tag properties. Anybody know a solution around this?
