An imported .SWF file generates no picture preview, but will export in the HTML page correctly if the size of the box into which it was imported is equal to the .SWF height and width. In addition, you need to change the Export As settings for the 'image' in the Modify dialog.
Follow these steps to get the .SWF file to export correctly:
- Go to item > modify
- Select the Export tab. (Export tab will only be available in Web Layout)
- In the Export As: field, select SWF.
- In the Export to: field, select image.
Note: Ensure that you have applied 'Fit Box To Picture' for the SWF.
