Picture in a topic

I have just finished a project, and I would like to put it in the “Finished work”. But the picture is more than the 200 kb witch is maximum. But most of all pictures is a lot over just 200 kb and these is in the topics anyway, just below the text. Please, how to do that?

upload them somewhere else, then link from here using the [img] button when posting.

Thanks :stuck_out_tongue:
