Look at sats/byte here and you can figure your image cost from there. Note that your image would actually cost more since you can't use all the bytes for image storage, some would be for image data, and you may have to split the image into multiple transactions.

At 4 sats/byte, 1KB is 4096 sats, 1MB is 4194304 sats which is $4,000 USD if I'm doing that back of the napkin math right
