Yeah, MacConverter works in both ways, is easy to use, very stable, and it's free. I can't live without it ;-) If you're downloading images, textures and the like with a Mac, Netscape (or whatever Browser you're using) sets the "Creator-Tag" to Quicktime by default. So you can open the file with the QT PictureViewer (which comes with QT) by double-clicking it. For use in Poser/Bryce etc. you don't need to convert it in any way! This is true as long as Quicktime can handle the graphic format: PICT, JPEG, TIFF, BMP, GIF, and many more. T. Lemke's GraphicConverter is a very usefull shareware app! It converts from (almost) any graphic format to (almost) any other, is a good picture viewer/browser, converts ASCII text (Mac <-> DOS <-> UNIX and some more), and comes with some basic paint features, so you don't need to open Photoshop or similar "monster app" for every little change.
