Question:
Images do not show up when I preview the Flash, what can I do to have them show?
Answer:
Flash can only support non-progressive j-peg images, so non-progressive is what you want jpeg images to be saved as.
Most jpeg images are saved as non progressive unless specified to be saved otherwise (with the major graphics editor Photoshop).
If you load up a jpeg image into your intro, if it doesn't play and it truly is a jpeg (e.g. you didn't rename a .gif to a .jpeg) then resave the image as a non-progressive image.
If you can edit the images you have and save them as non-progressive images then use them, then everything will work. Look for this option of saving as a j-peg without the progressive feature on the save screen of your graphics editor software.
If you don't know how to save them non-progressive, please see the help file of your graphics editor (search for the word "progressive" or "save progressvie")
