IPhotoDraw is a well-designed portable tool for annotating images.

You can add captions, arrows, lines, spline curves, bubbles, dimension lines, watermarks (including watermarking a batch of images in one operation) and more.

Whatever the object, you're able to set fonts, styles, shadows, glows, fill colour/ gradient/ image, line thickness, opacity and more.

Objects can be grouped/ ungrouped, sized, aligned, spaced, and positioned above or below each other.

If you're adding a lot of annotations then this can become complicated, but iPhotoDraw does its best to help. You're able to save snapshots of your current editing state - image + objects + the current settings of every tool - for easy restoration later. And unusually, iPhotoDraw never actually touches your original images, storing its annotations in a separate file (you export the finished image as a BMP, JPG, PNG, GIF or TIF file).

While it's not intended to be an image editor, iPhotoDraw has a few basic editing options: flip, rotate, brightness/ contrast and hue/ saturation adjustments.

A useful "Extended Toolbox" feature can add a custom shape to the iPhotoDraw toolbox. If you regularly use a couple of callouts in a certain style, for instance, set them up accordingly, add them to the toolbox, and they'll be instantly accessible in future.

There are some surprise bonus features, too, ranging from a simple screen capture tool to the ability to upload a finished image via FTP.
