Can an online doctor see pictures of my rash?

Yes - store-and-forward dermatology, where you send photos for a clinician to review, is an established part of telehealth, and skin is the specialty where remote care performs best. The photo technique that gets a useful read: natural daylight beats bathroom bulbs; take two shots - one close enough to show the texture of individual spots, one far enough to show where on the body it sits and how it spreads; focus matters, so tap to focus and hold still; skip filters and beauty modes; and include a coin or ruler for scale if you can. Pair the photos with the story - when it started, itch versus pain, what is new (soaps, foods, medicines, travel), whether it is spreading - because the image plus the history is the AI doctor consult. The honest limits: some rashes need tools a camera cannot replace - a dermatoscope for moles, a skin scraping, a biopsy - and the emergencies skip photos entirely: facial swelling or breathing trouble is 911, and a purple rash that does not fade under a pressed glass, especially with fever, is an ER.
