It is one of the unique "rites of passage" on this forum.
After you figure out the photo posting, they give you the secret handshake... :nana:
If you've got the pics in your album, you're almost there.
It may be harder to do on a phone. I usually have my album open in a seperate tab next to the forum tab for ease.
On a PC, you'd "right click" the photo and select "copy image location" (NOT "copy image")
Then, over the box where you type the text on the forum, you;ll see an "image" button. Clicking it causes a pop-up box, where you then paste your copied "image location".
Now, you just need to figure out what action replaces "right click"in the android world...
MTFBWY!
