Saving a file in jpeg format, you can choose the
compression factor (in Photoshop while saving there is an option "Quality", you
can choose a value between 0 - 12, and at the bottom of the window you can see
the size of the converted photo). For plant photos the value 8-9 is enough.
You don't need to spend a cent for a new photo
editor, just download Irfan View, it is free and very simple to use. The
compression factor is displayed in percents, I usually use 75-85% for web photos
depending on the colours (red details require higher quality).
I know that converting existing photos to a new
format would be very time consuming. When I started with Araceum, the most
common screen resolution was 800x600 px, so I was publishing photos in 300x400
px, and they are still there, but the new photos I add are larger.

Thanks Marek. I have
started adding a few in JPEG but with the thousands of photos already posted
on the site it would take forever to go back and convert them all. The
ExoticRainforest site has over 300 pages and some have 10 or more photos per
All the photos are converted in PhotoShop 7.0 and the
default for internet use in the program is GIF. If I convert in
PhotoShop to JPEG the files are twice as large as GIF. I'm sure newer
versions of the program do it better but since I'm retired I have no need to
spend another thousand dollars on a newer version. The original to the
photo you mentioned was in Photoshop PDF format, 11 megapixel and was
enormous. I would love to go back and reconvert that one but the
original file was accidentally destroyed so it is gone forever.

Anyway I must tell you it again - about your
photos. The GIF format reduces colors to 256 (look at the Philo leaves in
the photo "atrium combined"), the colors are not natural and
the file takes more than 400 kB of memory.
If you used the JPG format, the file size
would be smaller and in full colour.
