This photo detail is not ours, and it is not in the public domain, so
do not copy! This is a piece from a picture of school kids in Africa
using the same Linux computer systems we use in Takoma Park.
Stick with public domain photos, photos you have taken yourself, photos
you received special permission to use, or photos that have a special
type of creative commons license.
Here are some sources of photos you can probably safely use - but check
the details for each image. Most, but not all, can be used - at least
for private non-profit purposes. Remember - if you see a photo or
drawing at a website and it doesn't say whether it is copyrighted or not
- it is.
... and there are others.
Photo editors are nasty things to learn to use. Although the photo
programs all do more or less the same things, learning where the
controls are located and how to use them can be very, very difficult.
But once you have learned a photo editor - you can do amazing things. All of the 8.5x11 pictures hanging in the glass office were created on these machines, by children, using GIMP.
However this photo editor has virtually all the features of Photoshop (and some that Photoshop doesn't have) and doesn't cost $600.
By the way, G.I.M.P. stands for Gnu Image Manipulation Program.
Here are some lessons
Hints and suggestions from staff members and our computer community
Hints from Arlo, who used the user manual
Select part of the image, then go to the Image menu and click Scale Image... to bring up the image scaling
dialog. Change the numbers in the box or drag the image selection. Click the chain icon to keep the
height-to-width ratio the same.
Go to the Tools menu, then Transform Tools, then click Crop. Drag the mouse to select a rectangle to crop
the image to.
Go to the Image menu, then Transform Tools, then click Flip. This will flip the image on the vertical axis.
To flip it horizontally, hold down the control key while clicking Flip.
Go to the Image menu, then Transform, then click Rotate 90° clockwise to rotate the image 90° clockwise.
Click Rotate 90° counter-clockwise to rotate the image 90° clockwise.
