I was putting together a gallery of images and I wanted to use the artist's names for the images to make it easier to find the artists in a web search.

I used the technique of using the Placeholder > Replace with Graphic File to ensure the images retained their artist's names (each image title is the actual artists name).

When I previewed the uploaded gallery, all of the image appeared in my browser except three. When I looked at the three images that were not displaying, it dawned on me that all three had accented characters. I replaced the accented characters in each image file name, replaced them again as placeholders, and all three displayed fine.

I am not sure how if this would occur in countries other than the USA. But it is something to consider when using named files in your website.
