I have always saved images as JPG files in Photoshop to bring into
PowerPoint - or TIF if I wanted to change transparency. In my pre-PC
days, I never used PNG files as they were not really an Apple thing.
Now I see that PNG is the more-preferred choice. Can anyone tell me
what the differences are between PNG and JPG (or TIF) and when I would
use one format over the other? Thanks!

The publishing industry runs on TIFF and EPS but MS Office products seem to
have an unending stream of weird little glitches with both of these formats.

I'd avoid both when you're working with PowerPoint.

PNG supports transparency nicely and offers reasonable size compression with
*no* loss in image quality.

JPG is a good choice when you're working with photo-type images (not text and
other "hard-edged" graphics). It generally offers more compression (and more
control over compression) than other formats; it's a trade-off. The more
compression, the lower the image quality.
 
Hi Rebecca,
Here's complete explanation and comparison between different files or format: http://en.wikipedia.org/wiki/PNG

Because you're using Photoshop (PS): http://en.wikipedia.org/wiki/Adobe_Photoshop If you edited using Layer
function then I would suggest to save as Photoshop.psd (photoshop
ducument) and make a folder just to hold all .psd files. It is much better
& smaller file size than PNG. It is similar to Digital Camera RAW format
were you could make editing or correction any time you want it without
degrading of original element or no noise incorporated.

Using PS you could easily change your original .psd into many different
accepted formats and everybody chose the least file size for reasons you
already knew. We all preferred JPG, JPEG, or JPE they're all the same
and compatible format because of its popular uses. If you're BIG time web designer you chose PNG because it is royalty FREE.

HTH,
Rino
