Submit - source(alpha.png)

The images will be hosted on a site with different coloured backgrounds, so submitted images must be saved as alpha transparency png files (see below for information). This would suit subject matter which has been extracted, cut out, punctured, sliced, spliced, perforated or ruptured. Get creative with this.

Requirements:

• File size: Maximum 1280px x 1280px. 72dpi
• File format: Must be saved as a png with alpha transparency
• Number of entries: unlimited
• Deadline: open
• Content: must conform to the Tumblr community guidelines. Generally this means no violence, terrorism, hate speech or nudity*. Don't be a jerk
• Submit 1 image at a time, using the format: image, first name, surname, url(s)

Get in touch if you have an issue saving the file in the required format.

About alpha transparency png format

For an example see here: jsfiddle. The moon on the left hand side uses alpha transparency, this means the image can sit on any colour background. The moon on the right is made using indexed transparency. The index is set to white, it looks passable on the pale background, as the pixels are hard to decipher but on the darker background these become apparent.

* you might be able to get around the nudity clause if you can beat the algorithm. We don't want to censor work but ultimately it will be hosted on Tumblr and must conform to their guidelines.
