Use of Wikipedia images I created myself I have created several images for Wikipedia and would like to use them for my own poster/talks as well. However I am concerned that my colleagues will assume that I took them from Wikipedia and will consider it bad practice to use images from Wikipedia instead of my own and secondly to not reference them. How would you clarify that?
I think the problem here is that you (a) don't feel like you should be citing the source of this, since you made it yourself but (b) think this will be viewed as plagiarism from Wiki (or, at least, laziness). It seems to me the best way to resolve this is to cite your source, and cite it as yourself via Wikipedia. A short note like (Wikipedia, Original Artist Jane Doe) makes it clear that yes, this is the image from the Wiki page but also that you made it.
