I've imported my artwork from a photoshop file and created my project.
I'm amazed at how large the file has turned out.
One reason I can see is that everything that has been imported into FC from Photoshop has been saved as a png file.
For example I have a panning scroll panel image, which is 700k as a png and 150k as a jpg.
So no competition to which I should use!
Is there away to set the import correctly at the first stage rather than what I have to do now is resave all the assets as jpgs and in the project replace the images. doh!
I think the choice between jpgs and pngs is about image quality and Adobe decided to err on preserving quality vs. file size. They did not want people to import their PS file into FC and see jpg artifacts and blame FC for it. Flash Catalyst has some opmitization features that might help in the file size reductions.
