I don't have a ton of rules, but if you decide to use any of my icons, leave a comment (please) and DO credit rpgicons. (See here if you don't know how to credit.)
Please don't use my icons on web boards. These are made for journal RPGs. Also, do NOT hotlink ANY icons.
If you want to alter my icons in any way, shape or form, please comment on the post and ask before doing it. I'll probably say yes, but I enjoy knowing what people are doing with my icons.
Disclaimer: All of the icons were made for the purpose of recreation/entertainment; no profit is being made. There is no assocation with any of the people portrayed in icon batches. If people own photographs that were used for making icons there are any legal concerns or the like over them, or anything else, please contact me by posting to a moderator post and I'll get back to you ASAP and fix whatever it is. I don't take pictures that are labeled as credit to a specific person, but there have been incidents of websites taking photos and not crediting the original source.
