Editing pictures

Hi!
Is there any good program for editing the pictures of the coins? For example if I need to rotate the picture.
Thank You!

PhotoScape

 It is very good - it rotates images, crops a circle around a coin, and many other things. I first heard about it (and downloaded it) from the 'Your help matters' topic. The link is here ...

 There are picture examples above and below that reply.

 For example, to rotate an image, open the program, go to Editor then choose an image on your computer. Then choose the blue arrow icon going clockwise 'Rotate Arbitrary' which brings your image in a 'Rotate' window by itself, and choose the top left 'Rotate' tab. Then use the slider below it to turn the image either way round by as many degrees as required. Sounds complicated but it is not.  


 I can show working examples of rotating (to crop is already shown on the above link). You can also rotate and then crop the same image if required, before saving it; or the other way round, or individually. Here is a before and after picture of a coin in a holder which needs both rotating then cropping ...
                          


 Click on the PhotoScape desktop icon, and the image below appears. Then click on Editor (either from the circle of icons or on top row). Next image shows Editor opened.
                          
 With the Editor opened is a four-part screen; top left are the folders on your computer, which when on the selected folder then the images in there are shown lower left. On lower right are the controls to use, and above it is the window showing the image selected.


                          
 In the lower right panel are nine icons above the Resize button - choose the blue arrow mentioned earlier.
That brings up the smaller window, and I show above where I dragged the slider to the right by 13 degrees, thus making the image the correct rotation; note top left the 'Level Off' is not chosen but the 'Rotate' icon, and the 'Keep the original size' is ticked. Then click 'OK' and that window disappears, and is shown in the larger window on the original page underneath. Click on Save and that is it - or you can then go also to 'Crop' tab on lower left if needed. Again, all above is easy when a few have been done.  

P.S. That second image I saw somewhere, where both sides are in one image; and PhotoScape can work on those as well. So I would crop one at a time (which would also remove the slight top shadow) and save them separately, then later would rotate the obverse as well - to make two correctly aligned images.

Thank You very much, Zac!!!
