Okay, with Firefox it's extremely simple to attach photos.

-Access your Google photos however you get there.
-Click a photo so it's full screen for you.
-Right click on the photo and select "Copy Image Location."
-Type [img] then paste what you've copied next to your image tag a WITH NO SPACES. After you've pasted, again with no spaces, close the image tag by typing [/img].

Tada! You're done. Now, if you delete the photo in Google, the image disappears everywhere you ever linked it. Get into a fight on the internet and want to rage quit? Delete those photos in Google and they'll disappear everywhere. Have fun.
