The list of acceptable values for $type is short and fairly self-explanatory: "action", "app", "device", "filesys", "mime". The acceptable values for $prefix are the keys of the hash %dir_hash found around line 1550 of am_edit: "los", "lom", "him" and so on. The corresponding values in the hash indicate that the $prefix is used to indicate whether the icon is generic low-colour (256-colour palette), generic high colour (16/24/32-bit colour), or part of the Crystal SVG set, and its pixel dimensions if it isn't vector art. Bug 805: kregexpeditor.svgz -> hisc-action-kregexpeditor.svgz ? (That will get past the Perl check, and it's the $prefix/$type combination that makes the most apparent sense, but I don't know for certain if the author of the application would agree with me.) The other images are going to need to be checked for size and usage. Assign one of the prefixes "hi16", "hi22", "hi32", "hi48", "hi64", where the number matches the pixel dimensions of the image, and choose a type according to how it's used (or if you have no idea, "action" is probably a safe choice), and that will get you past the Perl check. (Not a Perl expert by any stretch of the imagination, but I can handle regexps and hashes.)
