I uploaded artidx.mul, gumpidx.mul and soundidx.mul files for 7.0.25.6 client. With art.mul, gumpart.mul and sound.mul generated by my converter tool (http://ruosi.org/load/legacy_uop_to_mul_converter/3-1-0-5) it can be used to view uo item's art, gumps and sounds in any viewer (fiddler, insideuo, etc.). Files will be auto updating with every new client patch but generator tool for that files will not be released ;)
