hey, angelgirl.
good questions. as far as the

i've almost used these several times...not to demonstrate something to someone here, but to demonstrate how it relates to me in real life.
for instance, in a ranting post i made the other day, i'd quoted something that my mother said and put

by it. it was what i was thinking about her statement. i later deleted it from the post tho for personal reasons. as for the demonstration image...wow, i could personally use that at times to explain what's going on in head with all the noise.
i agree with you, it might not be supportive to use those here in response to a post that someone has made personally...but they're great at explaining what i feel about the ppl IRL to gain the support that i need here. another instance...

i almost used to demonstrate how crowded my head feels sometimes. does that make sense? i hope so
so, while i agree that using the b.s. one to state that what someone said in a post was b.s. (not supportive), i think they're a great tool to demonstrate how a person may feel personally...
as far as using the angel girl in signature, i hope someone else can help you with that one. i have images in signature, but i actually had to type in a website to ontain those.
welcome and gl...just giving you another point of view on the images that could be construed as non supportive, but can be very good tools in demonstrating feelings that need support.
i hope you're having a good day
