Posting a picture in the lower portion is your signature. Go to User CP in the top banner. "Edit signature" will be in the same area as where you did your avatar. Whatever you put in the signature, pic or words, will appear in every post you make. To show pictures in the text box, which is what you want to do for show and tell, click on the "Insert Image" icon at the top of the relpy box. For both, pics need to be linked to a photobucket or other account.

I would go with the acetone, start with a quart. Brake cleaner is acetone based, but can also have other nasties in it like trichlorethylene, which could cause liver damage if enough gets absorbed through the skin. AutoZone and other supply stores carry acetone.
