a swf file is a container, and you just placed a jpg in it. That cannot make the end result smaller than what you put into it.
SWF makes really small files when you place vector items in it. But when you put big things like raster images or sound files, it will have to become larger.
jpg is pretty much the smallest and most compressed a file can get (although for a small subset of images, gif can be smaller). If your goal is to make smaller files, swf can only help if you can convert some of the image to vectors.
So when i take a jpeg image of 50k and use SFW, the "orignal tab" file size that is displayed at the bottom is what? why would they want you to know what that number is?
i’m not understanding this?

Don’t mind Don. He’s having a "Senior Moment" 🙂
He misinterperated your reference to Save for Web (SFW) for SWF which is a Macromedia Flash animation format. Hence all the "vector" and "sound" issues!
So let’s go back to the beginning.
When you look at the size of a Jpeg file (on disk) You read the "compressed" size.
For example. I’ve just opened a 30K Jpeg into Photoshop. the "reconstructed" image is actually just over 700K.
Saving for Web (at Jpeg 60 quality setting) will atually result in a new "compressed" size of 21K due to the stripping of the file’s metadata.
Hope this helps.

how do i convert to vector, i remember learning this is school but can quite remember how
haha SWF is almost like an abrv. for SFW or save for web. haha, it’s been a rought day for me aswell.
anyway,
is it possible to have the metadata "reinstated" if i opened it up in another program? say image magic?
i’m getting this reconstructed thing now, thanks!
by on disk you mean say microsoft explore/picture viewer?

Don’t you go having a senior moment on me too! 😉
The vector smector is irrelevent (see my last post.

ok sorry Chris, didn’t see the first part of you responce, it’s that bad a day…
get it now.
so when using SFW, PS is actually dropping Lossyness which inturn gives that grainy/distored result?
thanks again!
is it possible to have the metadata "reinstated"
Only be going back to your original file. (you did save the original, didn’t you?)
Once SFW has stripped out the data, it’s gone.
If you want to create Jpegs for the Web with their Metadata intact, use "Save As" instead and choose the relevant compression/quality setting manually.
Chris.
Saving as a Jpeg always destroys data. To compress the image up to 70% of the pixel information is discarded. When you open a Jpeg the program has to make and educated guess to reconstruct the image.
Several open/save cycles will result in considerable degradation of the image.
Best practise is to always save your images in a lossless format such as TIFF or PSD, reserving the Jpeg format (spit!) for the image’s final destination, be it web, email, or on screen presentation.
For quality work, Jpeg doesn’t really hack it.
Chris.
that’s what i thought. once it’s gone its gone, only way to get it back is from the og.
thanks Chris.
