JasperServer uses file extencion validation and for images supported only "jpg", "jpeg", "gif", "bmp", "png". So, I can suggest 2 solutions : Simple. Rename your SVG to PNG, and then rename uplocaded file in JRS repositry after uploading.Hack the sourceTo fix it in the source, find resource.add.files.js in scripts directory in your JRS installation ad find 'typeToExtMap' in it. Then find line "img": ["jpg", "jpeg", "gif", "bmp", "png"], and add your type. For instance: "img": ["jpg", "jpeg", "gif", "bmp", "png", "svg"]
