The eCard thumbnail images may appear misaligned on the donation or eCard page.
This could be due to page template design. If the page is only allotting a certain amount of width space for the column and your images exceed that space, then your images can experience wrapping to the next line. Resolution would be to adjust the image sizes or adjust the page layout/template column width for that space.
