You can scale down images to make the file sizes lighter.
Are you using the Clipping Frame (Insert > Media Objects > Clipping Frame) to add images to your file? If so, follow these steps to resize an image. If you are just working with an image in the workspace, without the clipping frames, just use steps 5 and 6 to downsample an image.
1. Double-click on a clipping frame image to enter into editing mode. The percentage indicator on the sliding magnification bar will tell you if the source image is large (12% is a very large image!).
2. Ensure the image is selected and click the Copy button.
3. Exit image editing mode by returning to the Sheet level by clicking in the document breadcrumb.
4. Paste the image into the document. It will be very big on the stage.
5. Scale down the down to a smaller size by grabbing a corner handle and scaling the image, or using Transform and adjusting the WIDTH AND HEIGHT percentages. (Conveniently, if you input 12% into the Width or Height box (while keeping the Lock Aspect Ratio option selected) the image scales down to the same size as the clipping frame you were using previously.)
6. Double-click the image again to enter into Bitmap Image mode and select Transform > Downsample to Screen.
7. Select the image and click the Copy button, then delete the image from the stage.
8. Double-click to get back into your clipping frame.
9. Select the image already in the frame, and delete it.
10. Click the Paste button to insert the new image into the clipping frame. It should display a better percentage such as 98 or 100%.
11. Save the file. You should find the file size to be much smaller now.
OK, looking over that now it is quite the list of things to do to optimize images for the screen. Hopefully there will be an easier way to downsample or optimize images for screen and print in the next coming releases.

Hi green_mamut,
I just downloaded all your images which you have uploaded in this thread, and it seems to me that you just renamed the extension of some of your images as jpg (rather than converting them to jpg's using some image editors).
For example, take a look at your "799px-Volvo_Ocean_Race_2009a.jpg" image property. You can notice that the thumbnail of that image says "jpg" where as the details pane tells that the image is in png format. I tried converting this image as jpg using mspaint and the size got reduced to 39.5 KB (where its was 349 KB previously).
The same is applicable for other images like, Volvo-Ocean-Race-volvo-1023287_534_800.jpg and vor_illbruck_1200.jpg as well.
I would suggest you to convert all your pngs to jpg images using any image editor and then you can check whether it has any impact on your SWF output.

Hello David,
I didn't did it like you wrote.
This images where only for testing.
How I'm doing it (all in photoshop):
1.I have a PSD File of my picture, this is for example 240mb because of all layers etc. and 4400x3000px in size.
2.Then I convert this to JPEG - and I save it with compression rate 12 - so no compression - the file is apx. 8mb now.
3.Now i resample the image to 600x400 and I'm using the function "save for web" - here I can select once more the compression between 100 - 0% and I choice 40% so a low quality . on the output I have an image of 50kb ...
I took the same picture that you choose and resample it on my way, on the quality that is acceptable it now 66kb
Now the same picture saved with Rome by using "export images as separate file" - the png is 618kb...
Looking forward for solution :-)
Greetings
M.

Ah yes, sorry, I see what you mean now GM. And yes, it does appear that Rome's conversion of images from JPEG to PNG does significantly inflate the filesize beyond a reasonable margin. For example, the 799px-Volvo_Ocean_Race_2009a.jpg startsat 189kb and ends at 1,180kb when Exporting Images as Separate Files.
Perhaps this should be logged as a bug?
