Interested in generating large photos?

Basically 2 questions:

  • How big can a photo (picture) be in jpeg format?
  • And how, suppose to create a picture of 50mb in size?

The size of the compressed image is not directly limited. Pixel dimensions are limited to 64k per side.
Generate - e.g. done via imagemagick

convert -size 10000x10000 plasma:fractal -quality 100 output.jpg

You will probably get a larger image, which you can then recompress a couple of times to find the right compression ratio.
You can compress exactly to size, for example, using the riot plugin for irfanview.
