ok im using flash 5 and photoshop to make an intro for a website. i have made graphics and material in photoshop and it is of a good quality, this quality is maintained when i import these pics into flash and appear with the same level of detail in the .fla file (im using .png file format). however, once i have exported my .fla to make the .swf file some quality is lost, when viewed with the flash 5 flash player it is still acceptable however when i view it in ie6 it looks really bad and im not happy if this is what it would look like when hosted on my site

basically can someone explain this to me am i doing something wrong maybe or is this a problem that happens a lot???
