African kids using the same computer system

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.

Hints  and suggestions from staff members and our computer community

Hints from Arlo, who used  the user manual

Scaling images:

  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.

Cropping images:

  Go to the Tools menu, then Transform Tools, then click Crop. Drag the mouse to select a rectangle to crop
  the image to.

Flipping images:

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.

Rotating images:

  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.

Image enhancements:

  Red-eye: Select a red eye, then go to Image, then Filters, Enhance, and click Red Eye Removal.
