I’m getting an issue when I load in a CSV Import that all the images work fine, but its also copying in the “ALT” tag which is displaying on mouseover, but its displaying to the old URL of the image.
The alt tag will include whatever Omeka can come up with as the “Title” of the file. If you set a Dublin Core Title on the File (not the Item, but the File) then we’ll use that.
If there’s nothing else suitable, we’ll use the “original filename,” which from CSV Import means the URL where the file was downloaded from.
