Selection of format?

Hello Everyone,

I am copying several photos from the Web and pasting them into a new
website.

I have found that the jpg format seems to be best in terms of quality,
permits use of filters in PS, and the file size is rather small.

When I use gif or bmp, I find the quality is not as good, the options in PS
are limited, and/or the file size is larger.

Does jpg format seem like the best choice for copy and paste on the Web in
terms of quality and size?

Thanks a lot,

Bob

I certainly hope the images belong to you, or you have permission.

File size of JPG images is a function of the amount of compression
applied and the image content. It's a tradeoff between size and
quality. You can use Photoshop filters because JPG is in RGB color
mode.

GIF is indexed color, and BMP can be indexed color as well. That
limits the options in Photoshop. They can be changed to RBG for
editing if you need to.

The best choice depends on the image quality and usage. GIF is
usually best for images containing large flat areas of color like
logos, whereas JPG is usually a better choice for photographic images.
JPG does not support transparancy while GIF does.

File sizes can be larger or smaller for either of the two, depending
on image content, compression, number of colors (in indexed color
images), etc. Try a 4-up comparison in "Save for Web" to see how
different options affect the quality and file sizes.

My only question is ... do you have permission from the owner of the web
site ??? If the images are copyrighted there is a $10,000.00 federal
copyright law fine when caught. If you have written permission, you are ok.
I'm a member of the copyright team from Professional Photographers of
America and we check these things out. So make sure you have permission
first.

The "pond' is actually just a depression where rain water collects. I guess
you thought it would be
fun to grab a copyrighted image. The fines are not a joke. Professional
photos are copyrighted and
the fines are as steep as illegally copying a VCR tape or a DVD. I was just
trying to point out to the
guy why he should make sure first before grabbing something copyrighted.
