Is your image crooked? Not a problem, there is a quick fix for that. Switch to Measure tool - under the droplet (Shift-I) and draw the line along your lines in the picture, which should be vertical or horizontal. It could be the horizon line or a wall of a building - simply mark the line that should be straight. And the go to the main menu - Image, Rotate Canvas, Arbitratry. The angle will be already there. Press OK and here it is - your image is straight, you just have to crop off the unwanted areas.

Have you ever tried to precisely crop an image when there are just a few pixels that you want to get rid of? The crop tool just snaps to the document border or to the layer border. Sometimes I just zoom in to make the difference much larger and then adjust the crop area.
But there is a better way - Hold Ctrl key (or Command on Mac) and adjust the crop area to precisely crop your image - down to a pixel.
As well when you use your crop tool you can easily move the crop area with the arrow keys and zoom in/out with Ctrl/Command "+/-" keys.

Do you have some great photographs that people probably would want to buy? Do you want to sell them? Well, there are multiple choices to do it, and you probably know some of those.

Unlike other services charging fees for reselling images, we believe that photographers should not have to pay anything, and we will bear all the associated hosting/storage expenses. The service is completely FREE.

Anyway there are already some photographs that are nice to look at.
