As basic as it gets
Have you ever seen one of those "Russian wedding photoshop" pictures? Yes, there's something not right with them. It's usually the composition, but most often than not the general idea denotes bad taste. This distinguishing performances require tools too coarse for Photoshop to handle. Only cheap photo editor programs can rise up to the occasion to produce such masterpieces.
Here we have a good candidate. Magic Photo Editor is a simplistic image editor that doesn't deal at all with image properties and quality, but instead focuses on mimicking the play with stamps and stickers on a colored board, the board being the image that you want to "edit".
Besides clip-art style objects, you can add in other images (with gradient transparency), speech bubbles and rich text. You can also select a themed border from a modest gallery. Speaking of modest, everything looks and feels like a work in progress. For example, images have anchors, but not all of them work intuitively. If you want to change the size of both dimensions you can only pick the bottom right anchor. Even so, there's no way of preserving the image aspect, so you need a very steady hand.
Magic Photo Editor seems to be designed for kids. However the difficulty of handling images is a very powerful counter argument to my supposition.
