18.1.2 Mail Settings
The right part of the dialog is used to change the settings of the images to be sent. These settings
will be remembered when you close the plugin until you change them.
Select your favorite e-mail client from the drop-down menu. Default is the current email pro-
gram set in KDE System Settings.
If youselect Attach aﬁle with imageproperties from
the comments, rating or tags
included with the images will be merged to atext ﬁle and attached in the mail.
The next three itemsallow you to set-up the image properties to be sent. To enable these options
check Adjust image properties. First select an Image size suitable for your Internet connection
speed and the target mailbox size.
The PNG format inthe Image ﬁleformat drop-down menu is not well adapted to reduce photo-
graphic imagesﬁle size, but is best suited for compressing losslessitemslike the TIFF ﬁle format.
PNG must be used if you use dialup speed Internet and you want to preserve the photo quality.
Otherwise, JPEG is the recommended format.
The Image quality can be chosen with the input box. 75% is the standard compression ratio
for JPEG ﬁles. Setting compression to 100% will result in lossless compression at the cost of the
largest ﬁle size. The difference in ﬁle size between 90% and 100% can be quite dramatic, whereas
the gain in quality is minor. Very good quality is already obtained with 85% compression.
If you choose JPEG as the Image ﬁle format and the original ﬁles were in JPEG format, the original
Exif data included is preserved in e-mailed images.
