How can i draw jpeg graphics by glade
 

The data of jpeg comes from the net.I want to build the jpeg in my memory of the computer and display it on the window that build by glade.How can i do it?Please tell me.Thank you very much.

this has nothing to do with glade. glade is just a ui build and callback stub creator. not sure what building a picture in memory means, but you'd want to be using a GtkImage to display a picture though: http://www.gtk.org/api/2.6/gtk/GtkImage.html

Thanks for acid_kewpie's illustration.
