Here I posted a picture and then added a link to it. The picture in itself is rendered into an illegible thumbnail, and the explicitly entered link overrides the implicit link which would invoke the "picture/attachment magic". How can a user see it, then?
I admit that this is a tricky issue and I don't want this to be solved in any way. I can simply modify that post (I deliberately left it so so that I can make a point here, and it probably won't harm the OP anyway). Just maybe something to think about.
I would like to request an attachment of the picture in it's original resolution in this thread or via PM.
Once I have the attachment I will look into a possible solution. If there is no immediate solution I can definitely add it to a list of future improvements.
