Manipulation?

Ok, I know how to code double and triple expands thanks to this site, but how do I do manipulation? I currently use Sumopaint.com for everything, I think it has the same tools. Could someone please please tell me how to do manipluations?

For manipulations, they basically consist of images placed on other images.
Start with a basic manip, such as a horse or dog in a forest, etc.
To start, you'll need to first cut out your horse from his original background. To do this, you'll need to use a cutting too or erasing tool of some sort to get rid of his original background to just leave the horse.

Next, you'll need to place him on the background you've chosen, by moving him into the position you'd like on the background.

That's a basic manipulation, and don't forget that you can always go further, and try using lighting techniques, removing halters, placing grass over hooves, and even re-painting manes and tails.

Good luck!
