72 vs 96 dpi for Flash

I know this is an old question, but I'm wondering if there has been any consensus over the last year or so since CS3 has taken off for the preferred and best output of images. Is 72 dpi still the way to go, or is anyone out there using 96?

72, if I bring things in at anything else it is larger and I have to resize it down. Many times I am taking images that were used in print at 300 dpi. If I just crank down the image to the pixel dimensions I need and do not change it from 300DPI. When I import them into Flash CS3 they are huge and need to be resized (in flash).
- it's kinda stupid, the image is 200px by 300 px any way you look at it. but not in flash.mrdobolina
- Right, you should always use 72 dpi for web.falcadia
- well in html it shouldnt matter, just the pixel size but in flash it matters.mrdobolina
- to match the monitor. Although they are same w & h.. they are not the same resolution.falcadia
- No it does matter in html. You can constrain the image but if you view the actual image it will be huge.falcadia
- Which will add tons of load time. If it's at 72 dpi it will stay true to it's dimensions.falcadia
- You can bring a high-res into flash but when you export flash uses it's publish setting to compress to 72 in the swf.falcadia
- there are still the same number of pixels though.mrdobolina
- in html I mean, not flash which acts wanky.mrdobolina
- How so? 72 vs 300?falcadia
- Changing your width & height does not affect your resolution. If you use 72 no resizing nessacary.falcadia
- make two images, identical, make one the same amount of pixels but 300 dpi, same number of pixels, the pixel is the same size.mrdobolina
- the same siz3e whether it is 900dpi or 10mrdobolina
- Not when viewed in a browser.falcadia

When you compile a swf flash does the compression anyways. It makes more sense to bring them in at 72 with correct demensions etc.

72... 96 sucks. I dislike resizing too.

I use 300dpi images, print them out, fax them to myself a couple of times, then scan them back in at 72dpi, trace to vector and then import into Flash.

hmmmmmm......
hence why I'm asking:
"Way, way back in the infancy or digital graphics and the Internet, some experts did suggest that an output of 72-96 ppi was appropriate for screen images. Those numbers were based on the fact that the standard Macintosh monitor of the day left the factory set at a default screen resolution that resulted in 72 screen pixels per inch, based on the viewable area of the monitor screen. The standard PC setting delivered 96 screen pixels per inch."
Am I beating on Mr Ed while he's down?

A simple test....
Take a 300 dpi jpeg and upload it to a server.
Take the same jpeg and change it too 72 dpi but keep the same width & height.
Then view the jpegs on the server (
)The 72 dpi image will be the exact 200px x 300px or what ever your dimensions are and the 300 dpi jpeg will be more like 1000px x 1200px

96 dpi is what happens if a user chooses Large Fonts from their display settings in Windows.

but then take that same 300 dpi image and make it 200x300 and you have an identical image, unless it is in flash.
- Same width and height yes. but why do that. Only adds load time. Plus the quality might go down.falcadia
- no more load time, same number of pixels.mrdobolina
- No it not. It's still 300 pixels per inch just squished. Look at the file size difference.falcadia

72dpi and 96dpi dont mean anything. apple did a monitor once that was exactly 96dpi, but really, it's dependant on the physical size of the monitor. I have some notes on a lecture I did once, I'll upload them if anyone's interested. I was determined to explain it properly once and for all!

You are right. Flash reads dpi the same as your browser or monitor would when you bring it in. In flash if you resize to 200x300 then export. Flash takes those dimensions and compresses it to your jpeg quality settings (usually 72 or lower) and compiles it to a swf.
- Although, the actual image in your library is still 300dpifalcadia

don't cha mean ppi!?
- well yeah but that is another argument :Dmrdobolina
- Ha! yea. whatever.falcadia

dpi really is irrelevant until you print and image, but flash gets tricky with it for some stupid reason. if you import 2 images to the stage, both 300px by 200px, but one is at 1dpi, the other at 1000dpi, they will indeed look different on the stage, but if you select them and type 300 and 200 into the property inspector, they will both look and export identically. a 300 x 200 image contains 60,000 pixels no matter what the dpi is.
