I tried to replace the start logo in lubuntu and this is what it looks like now. Top left logo.

I don't know if it was the wrong size or what happened with it.

Does someone know what size it needs to be and what file format it needs to be saved as?
What if I wan't to get the default logo back as the start logo where would that logo be saved at?

Well everything you do to your LXDE Panel is stored in a config file. If you just want to nuke it and start again the easiest solution would be.

sudo rm ~/.config/lxpanel/LXDE/panels
sudo cp /usr/share/lxpanel/profile/default/panels > ~/.config/lxpanel/LXDE
lxpanelctl restart
