Create quality web graphic cards

I have pdfs of 10 or so greeeting cards that I want to put online in an online card shop. I need the pdfs turned into images that I can embed on the web in flash where the the text (there is a lot of it) and images are clear and of a size that will fit on the screen.? Examples of my efforts to date can be found at <[login to view URL]>? ? The first and third cards in the top row have live links to the flash files showing the need for the clear crisp files on the individual card pages and the amount of text and graphics on the cards. My plan is to create a powerpoint of each card and then convert the powerpoint to flash to people can click through the card, but the images need to be bright , sharp and readable at a size that fits.
