but I don't do it these days because it disrupts my formatting
Include the source of the image, "in the image". I understand you completely about that, for me it's the esthetics's that play a important role in a post, so to "avoid" that "ugly"(at least to me), Source below the image or in the note at the end, I put it "in the image", people can open the image in a new tab and "land" on the source.
That's an interesting idea, but it doesn't satisfy creative commons where you have to link to the license also... but maybe footnotes at the bottom of the post are the best way to go (along with linking to the original image). Good thoughts all. Thanks.
Well I try to avoid creative commons as much as I can, even if I end up with "bad images", or I'll by some cheapo stock images and edit them to look better, or use images labeled for reuse, or ask a photographer friend, or look in my 23 Gb photography archive... so there are many ways to do it the proper way. At least for me...
