If you have been using your computer for some time, you already have separate applications installed for image editing and drawing. But if you are using somebody else’s computer, you might not have the administrative privileges required to install new programs. In this case online apps come quite in handy. Rather than looking for separate web apps for image editing and drawing, you should pay a visit to “Mugtug.”

Mugtug is a free to use web service that offers two web apps – an online image editor and an online drawing tool, both HTML5-based.

The site also has a small community which users can log in to share the work they got done through Mugtug.

The online image editor is called “Darkroom” and offers a number of impressive features.

You can upload an image to the editor from your computer, a URL, or through your Picasa or Flickr accounts. Once uploaded you could use one of the basic features from the top pane. These features include rotate, mirror, crop, and red eye removal.

Further options can be found in the left pane. Here you can set the colors, set the brightness and exposure levels, and modify the contrast and saturation levels.

You can also add effects to the pictures. Previews of each effect can be seen by placing your mouse pointer over the effect.

When done editing, you can save or share the picture using the button on the top left. You can do a final resizing of the picture and choose to save the picture, share it via URL, or publish on your Picasa or Flickr account.

The drawing app offered by Mugtug is called “Sketchpad.”

This tool offers standard drawing options along with advanced features of pattern, gradient, and swatch. You can also create your own colors using the color chooser set in the top right. When done drawing, you can use the button in the top right to save your drawing in PNG image format.

Mugtug successfully merges these tools in a user friendly interface. The next time you need to draw or edit a photo, remember to visit Mugtug.
