Hi, I write because i am looking for a program that imports in mass simple images (jpeg, bmp etc) and creates for each of them an image 4 times bigger, composed by the original image copied and mirrored.

Let me explain: in the final image, in the top left there is the original image, in the top right the original image mirrored by the vertical axis and in the bottom these 2 images mirrored by the horizontal axis.

Do you know a program that do this, apart from photoshop?

I don't want to install photoshop because I already use fireworks for all the common graphical operations.

Thank you

Fireworks can do that.

Just create a blank document 4 times larger than your picture, then paste it into the top left. Duplicate the layer 3 times, then flip them as intended. I've not used Fireworks in ages, so I've no idea where this option is. You could try Edit > Transform.

Or, post it here and I'll do it for you in Photoshop in 2 seconds.
